Whether you’re going on an overnight or an entire thru-hike, finding the best backpacking backpack is key. To find the perfect pack, lead tester Nick Belcaster has spent years living out of haulers from the high-desert heat of the PCT to the tundras of Alaska. During the most recent testing season, he hiked 100+ miles in Washington to test four of the newest packs in 2026.

Our team’s rigorous testing highlighted the standards of the category, including the top-choice Gregory Paragon/Maven and the budget-wise REI Co-op Trailmade 60 for new backpackers. From expedition packs to nimble weekenders, we have vetted the bags that provide genuine comfort and capability.

This guide is built on a decade of outdoor experience and a deep understanding of load-carrying tech. We’ve sifted through the marketing jargon to curate the best backpacking packs available today, ensuring your gear stays organized and your focus stays on the horizon.

Editor’s Note: We updated our Backpacking Backpacks guide on November 13, 2026 to reconfirm our top picks as well as reorganize how we review them. We also made sure our picks were still widely available, and at the price they should be.

Nick Belcaster

Bottom Line: The best backpacking pack for most hikers, balancing a lightweight build with a heavy-duty suspension capable of handling multi-day loads.

The Gregory Maven 58 (women’s) and Paragon 60 (men’s) ($300) are smack-dab in the middle of Gregory’s lineup. While not as ultra-rugged as the heavy-haul Baltoro or Katmai series, they are noticeably more refined and supportive than entry-level packs like the Zulu or Jade, offering an ideal sweet spot of weight savings and load-bearing comfort. For most hikers, these packs are going to do the trick.

The Tech: The pack revolves around the hips (literally). The FreeFloat dynamic hip belt pivots with the body’s natural motion, and when Mary Andino tested the pack over 3 days and 40 miles on Minnesota’s Superior Hiking Trail (hauling a full overnight kit plus bear canister) it was a revelation: for the first time on day three, her hips didn’t protest at all. The AirCushion mesh back panel also excelled at breathability in 80-degree weather. However, despite adjusting through the four available torso height settings, Andino experienced nagging upper back pain between her shoulder blades, proving that getting the exact torso match is crucial with this frame design.

What We Like: Practical organization shines throughout. A massive side-zipper access lets hikers quickly reach deep into the main compartment without disrupting the pack job, and Gregory smartly kept the side water bottle pocket intact right alongside it. Andino also used the Maven as a heavy-duty crag bag while sport climbing at Jackson Falls, Illinois, where it easily swallowed a 70-meter rope, helmet, quickdraws, and a stick clip on rugged approaches. Fine details are exceptionally well thought-out, like the shoulder-strap mesh pocket built specifically to lock down a Garmin inReach without annoying bounce.

What We Don’t: The large external stretchy mesh pocket secured with a vertical buckled strap could stand to come up higher; bulky items like a camp chair can shift around and raise concerns about falling out. Additionally, the hip belt pockets are a bit too small to securely fit a modern smartphone, and unlike competitors like Osprey, the Maven does not include a built-in rain cover. Finally, the persistent upper back discomfort Andino felt during long mileage highlights that the frame sizing range may not fit every torso shape equally.

Should You Buy It? For backpackers looking for a reliable all-rounder that slashes weight without sacrificing heavy-load stability or breaking the bank, the Maven 58 and Paragon 60 are easy to recommend.

Nick Belcaster

Bottom Line: A budget-friendly entry point built with a surprisingly comfortable hip belt and an accommodating adjustable frame.

The REI Co-op Trailmade 60 Pack ($189) isn’t studded with high-tech bells and whistles, but it easily carries a full weekend’s kit. Aimed at bringing new blood and diverse body types into backpacking, this pack delivers a robust package that hits an accessible price point without sacrificing core comfort.

The Tech: The standout tech of the Trailmade 60 is its exceptionally plush and supportive hip belt, which offers a wide sizing range and two generous pockets. When tester Ian Graber-Stiehl tested the pack over 30 miles in the Southeast (pushing loads north of 45 pounds), the dual-ridge back padding and curved lower back support kept his back comfortable. Sizing accommodations are robust, and it has an adjustable torso (via a simple central webbing system) and a fixed price across all sizes for both men’s and women’s versions. The pack is made from 100-, 200-, and 400-denier recycled nylon materials, and adds a new U-zipper to the exterior of the pack in the most recent iteration.

What We Like: Smart touches make the pack welcoming for newcomers, including packing instructions and a helpful QR code printed directly on the inside of the non-removable lid. External handling benefits from low-angled water bottle pockets that easily accommodate 1.5L Smartwater bottles and offer fantastic on-the-go access. Graber-Stiehl also appreciated the inclusion of bilateral top and bottom daisy chain loops for attaching gear. Stacked against pricier alternatives like the REI Flash 55, the Trailmade wins out on waist belt versatility and total volume for a lower investment.

What We Don’t: There are a few compromises: The pack has to save money somewhere, and the 100-denier nylon on the main exterior isn’t the most rugged out there. The pack does patch on some more typical 400-denier nylon on the boot of the pack (where it touches the ground), as well as a 200-denier lining, but long-term durability of the main pack body will suffer a bit. The new external U-zip also gives pause for long-term durability, though we haven’t seen this happen yet.

Should You Buy It? The Trailmade 60 is an ideal, forgiving companion to help newcomers test the backcountry waters, though experienced backpackers with dialed systems may eventually want to step up to a slightly more refined model.

Read Review: Osprey Exos 58 Review: Popular Lightweight Backpack Gets Better

Bottom Line: A featherweight pack with a tensioned trampoline mesh back panel that keeps air moving (and your pack well-balanced).

The Osprey Exos and Eja 58 ($285) packs have been top lightweight picks for long-distance backpackers and weekend hikers for years. Offering a remarkably breathable design at roughly 2.75 pounds, the series manages to keep overall weight impressively low without going completely bare-bones.

The Tech: The big news is Osprey’s AirSpeed 3D tensioned suspension system, which is anchored by a 4 mm alloy perimeter frame and an open mesh back panel. When tester Seiji Ishii loaded the pack with 30 to 40 pounds of gear across multi-day summer trips, the spongy, dense foam in the shoulder straps and springy frame provided an exceptionally comfortable ride. The generous gap between the pack body and the spine created standout ventilation that easily dissipated heat in the hot and humid Texas conditions. However, the movement of the suspension can create some instability when tackling techy scrambles with the pack fully loaded, making it best suited for moderate trails.

What We Like: Dual-access stretch mesh side pockets easily swallow 1.5L bottles and tent poles simultaneously, while the zig-zag compression straps can be tensioned independently and routed either over or under the side pockets. The front shove-it pocket offers versatile, quick-access storage for layers and gear, secured by a single webbing closure. Other thoughtful touches include a removable floating lid with an integrated FlapJacket cover to protect the pack when the lid is stripped off to save weight, plus ice axe and trekking pole attachment points.

What We Don’t: Because of the tensioned pack frame, the bag cannot stand upright on its own, requiring you to constantly prop it against something while loading or unloading. The lightweight stretch-mesh on the exterior body pocket will also eventually gather holes and sag, but this typically takes a few hundred trail miles before starting.

Should You Buy It? For weight-conscious backpackers seeking a light setup that doesn’t sacrifice plush comfort or ventilation, the Exos and Eja 58 packs are a great choice. Those needing a bit more support and comfort should look at the Gregory Paragon/Maven tier of packs, but the 2.5-3 pound weight on the Osprey means this bag won’t drag you down before you even open the lid.

Nick Belcaster

Bottom Line: A weather-resistant pack built from innovative Woven Dyneema Composite Fabric, designed for the high-wear demands of long-distance thru-hiking.

The core line of Hyperlite Mountain Gear packs has received a major update, bringing fresh refinements to longtime favorites. The Hyperlite Mountain Gear Southwest 55 ($420), along with the Windrider and Junction packs, are now trimmed out in brand-new Dyneema Woven Composite fabric alongside a redesigned exterior that makes accessing gear even easier.

The Tech: The new fully woven Dyneema Composite Fabric (3.9 weight) is made with a 200-denier woven Dyneema face fabric, and matches the weight of previous 50-denier white DCF while drastically improving abrasion resistance. When Senior Editor Nick Belcaster put the pack through a ~40-mile circuit around Cerro Huemul in Patagonia, the pack emerged completely scratch-free. Suspension is supported by twin aluminum stays and a newly sewn-in foam back panel, while redesigned shoulder straps gained an increased curve around the neck for improved ergonomics.

What We Like: The compression straps are now modular and attached with lark’s head knots and quick-release buckles so they can be quickly adjusted or completely removed. The outer shove-it pocket is pleated for extra storage volume, and the side bottle pockets have been lowered to make grabbing 1L Smartwater bottles much smoother on the fly. The updated fabric is wickedly impressive as well, and the long-term durability differences are stark.

What We Don’t: Like all Hyperlite packs, the Southwest lacks load lifters because the twin aluminum frame stays don’t extend above the shoulder strap attachment points. Belcaster notes that while the frame handles loads comfortably for typical lightweight setups, it performs best when kept under 50 liters or below 35-40 pounds. Additionally, the premium price tag remains a hurdle for budget-conscious hikers.

Should You Buy It? For ultralight backpackers seeking top-tier weather resistance and long-term durability that can shrug off abrasive off-trail abuse, the Southwest 55 is a great gear investment. The recent updates make this pack feel like it earns every dollar it asks for.

Nick Belcaster

Bottom Line: A rugged, utilitarian expedition pack constructed with Challenge Sailcloth Ultra 400X and 200X fabrics for exceptional abrasion resistance. It’s a classic design done in the most durable way possible.

ULA Equipment has earned its reputation on the backs of thru-hikers over thousands of miles. Based on a classic blueprint but wrapped in ultra-rugged materials, the ULA Ultra Circuit ($380) is a tough-as-nails option that balances high load capacity with robust durability.

The Tech: The pack is what it is thanks to the Challenge Sailcloth Ultra 400X and 200X fabrics, which provide high tear strength, UV resistance, and some impressive inherent waterproofing. When tester Jackson Sims-Myers put the pack through an overnight canyoneering trip in the Grand Canyon, the fabric emerged remarkably unscathed, save for a small hole in the outer mesh pocket. Suspension is handled by a 1.2-ounce carbon fiber and Delrin suspension hoop, a dense internal foam frame, and a single aluminum stay. ULA also offers exceptional sizing customization, with torso lengths ranging from small to XL and hip belts from XS to XXL, plus interchangeable J and S strap options.

What We Like: Large, waterproof-zippered hip belt pockets make accessing snacks and small gear effortless on the go. The top compression system offers a choice between a single strap or a Y-strap configuration, making it easy to secure bulky items like a bear canister (which can also fit vertically inside the pack). Additional thru-hiking essentials include dual ice axe and trekking pole loops, plus ULA’s four-point-contact hip belt system that maximizes adjustability and comfort.

What We Don’t: Despite its water-resistant fabric and roll-top closure, the pack is not seam-taped, meaning hikers will still need a pack liner to keep gear completely dry in heavy rain. Additionally, the G-hook connections on the optional top and bottom straps can become detached when snagged. The stiff ULTRA fabric side pockets make cinching and retrieving larger 1.5L water bottles a bit challenging, and the curved bottom prevents the pack from standing upright on its own while packing camp.

Should You Buy It? While hikers on well-maintained paths might save a few dollars with the standard Circuit, those facing abrasive environments and heavy loads will find the Ultra’s armored skin well worth the upgrade.

Cons

  • Heavy pack by itself
  • Not very versatile for lighter trips
  • Price
Nick Belcaster

Bottom Line: An expedition-worthy pack with an enhanced frame to carry heavy loads, balancing massive carrying capacity with a heavy-duty suspension.

The Gregory Baltoro 100 Pro ($460) is designed for the haul-it-all crowd whose gear lists include packrafts, SLR camera kits, or expedition tents. Positioned as the ultimate heavy-hauler at the top of Gregory’s lineup, it functions less like a standard bag and more like an extension of the body when crossing into heavy-load territory.

The Tech: The core of the pack’s load-bearing ability is the FreeFloat A3 suspension system, which fuses a rotating hip belt and dynamic shoulder harness that pivot with natural body movements. To prevent barreling under heavy loads, Gregory reinforced the Pro edition with a beefed-up perimeter alloy frame and a thicker HDPE frame sheet. When side-hilling, the independent rotation keeps the 100-liter load centered, even when carrying loads upward of 50 to 75 pounds.

What We Like: Organization is exceptionally well executed for pretty much any type of gear. A massive U-zip main front opening allows quick access to items deep in the pack without disturbing the entire load. The angled SideWinder bottle holster remains a stand-out feature for smooth one-handed Nalgene retrieval while moving. Additionally, the oversized hip belt pockets comfortably hold satellite messengers like a Garmin inReach Mini, and the tough 210-denier and 630-denier nylon body holds up without needing to be babied.

What We Don’t: The trade-off for this structural integrity is considerable bulk and mass. Weighing in at over 6 pounds empty (for the Large size), it’s likely out of the question for ultralight hikers. When loaded under 30 pounds on lighter weekend trips, the suspension feels excessively rigid and overbuilt for the task.

Should You Buy It? For gear-intensive mountaineering, packrafting, or multi-week expeditions where a 100L capacity and maximum stability are mandatory, the Baltoro 100 Pro is a workhorse. It’s a niche option, but if you need the support, it’s one of the best out there.

Cons

Nick Belcaster

Bottom Line: A specialized pack built for mountaineering and heavy expeditions, hanging on a heavy-duty suspension system tailored for moving massive weight.

The Mountain Hardwear AMG 75 ($470) is a sport-specific load hauler designed to transport large, technical kits to remote locations. Positioned as a dedicated alpine workhorse, it is the exact pack to grab for equipment-heavy adventures like mountaineering, where a robust frame is required to haul ropes, crampons, or avalanche tools.

The Tech: The center of the AMG series (which also comes in a 105-liter capacity) is its frame and harness system, which uses multi-density foam padding contoured for maximum load transfer. The hip belt mounts directly to the bottom of the frame hoop and pivots with body motion. When tester Scott Wilson carried a 50-pound loadout over a 6,700-foot mountain pass during an eight-day, 110-mile packrafting expedition across Alaska’s Brooks Range, this direct frame connection provided excellent stability, proving why the pack is a frequent sight on Denali’s Kahiltna Glacier.

What We Like: The build quality and alpine-specific feature set are exceptionally rugged. The pack body utilizes a UHMWPE-infused 200-denier ripstop fabric paired with an ultra-thick 840-denier nylon bottom that survived Alaska without much of a mark. Dedicated gear storage includes a quick-access front avalanche tool pocket, sled-tow attachment loops on the hip belt for glacier travel, and a full-wrap compression system that shrinks the bag down when not running at full volume. Except for a bulky PFD and paddle, Wilson was able to stow his entire multi-day kit inside the pack.

What We Don’t: Sizing availability is a primary drawback, as the AMG 75 comes in only two sizes (S/M and M/L). While this covers a broad range of hikers, smaller adventurers like Wilson found the hip belt slightly too loose even when cinched down completely on the S/M frame. Additionally, the nearly 5-pound empty weight makes it a poor option for anyone looking for a single do-it-all backpack for casual weekend trips.

Should You Buy It? For mountaineers, winter expeditionists, and packrafters needing to haul heavy, abrasive equipment over rugged alpine terrain, the AMG 75 is a top-tier choice. For those seeking a lighter, more budget-friendly climbing pack, options like the Black Diamond Mission 75 ($350) save weight and money, but the AMG 75 reigns supreme for pure carrying comfort under maximum load.

Read Review: Osprey Aether 55 and Ariel 55: The Cadillac of Backpacks

Bottom Line: A traditional, heavy-duty pack that excels in custom-tailored fit and rock-solid stability under heavy loads.

The Osprey Aether 55 and Ariel 55 ($350) are the heavy-hitting workhorses of Osprey’s lineup, designed for backpackers who prioritize plush comfort and load-bearing capacity over saving ounces. Built entirely with Bluesign-approved, PFC-free materials, these packs use a rugged 420-denier nylon construction on both the main body and the high-wear bottom panels.

The Tech: The structure centers around a stiff Lightwire frame, a rigid frame sheet, and a die-cut foam AirScape back panel. What sets the Aether and Ariel apart is their deep adjustability: every point of contact is customizable in multiple dimensions, allowing users to adjust torso length via webbing ladder locks, modify shoulder strap and hip belt length, and fine-tune both the height and angle of the hip belt. When backpacker Seiji Ishii put the pack through a 2-day test (intentionally loading it down), the suspension directed almost all weight to the hips and lumbar pad with little load on the shoulders. However, that rigidity comes at a cost: weighing in around 5 pounds empty, it lacks ultralight status and restricts twisting torso mobility.

What We Like: While Ishii preferred loading from the top for efficient compaction, reaching camp highlighted the utility of the large zippered front panel, which allowed him and his hiking companion to easily pull out split tent pieces and cooking gear without laying equipment onto wet ground. Ample external storage (including dual-zippered hip belt pockets, stretch-mesh bottle pockets, and a front shove-it pocket) kept essentials handy, and Osprey thoughtfully included a custom rain cover that you can deploy when needed.

What We Don’t: The pack’s significant weight (ranging from roughly 4 pounds 13 ounces to 5 pounds 5 ounces depending on size) makes it a poor choice for lightweight hikes. Furthermore, the stiff perimeter wire and frame sheet reduce upper-body agility, making the pack feel cumbersome on technical trails. If you need a pack to move with you, consider the Mountain Hardwear Kazam or Gregory Paragon.

Should You Buy It? For backpackers who prioritize maximum comfort, robust durability, and flawless load stability over minimalism, the Aether 55 and Ariel 55 are phenomenal choices.

Nick Belcaster

Bottom Line: A streamlined roll-top hauler that strikes a balance between sub-3-pound weight and foundational frame support.

The EXPED Lightning 50 ($270) lands right in the sweet spot between an extended day pack and a light-duty backpacker. With a clean Swiss design aesthetic, it sits as a value-focused entry in the lightweight category and comes in a good bit less expensive than comparable packs. During 3 months of testing in Colorado’s central mountains by tester Bergen Tjossem, it handled most loads with ease.

The Tech: EXPED’s “T-Rex” frame is a single vertical aluminum backbone that prevents the pack body from barreling out, no matter how tightly stuffed. The upper back panel and shoulder harness adjust smoothly along this metal spine, offering an impressive torso range (17–20 inches for S/M and 19–22 inches for M/L). When Tjossem tested the L/XL frame across early summer hikes, the compact back pads provided some great breathability by minimizing back contact. However, EXPED’s aspirational 48.5-pound max load rating proved a bit unrealistic: on a trip carrying 39 pounds of gear, Tjossem found the small lumbar pad and hip belt pinched and required some overtightening to manage the weight.

What We Like: The open-ended roll-top design easily expands to accommodate varying gear volume. During a May trip near Vail Pass, Tjossem packed a Big Agnes Tiger Wall UL tent, 0°F sleeping bag, MSR Windburner stove, and cold-weather layers without fighting the main compartment. Outside storage is exceptionally practical, with some voluminous hip belt pockets, an expanding front mesh pocket, low-profile side water bottle pockets, and top hooks that secure a sleeping pad or jacket. The exterior is built from 210-denier HMPE ripstop nylon with a 600-denier polyester bottom, which easily survived bushwhacking through overgrown forests in Colorado’s Gore Range.

What We Don’t: Exterior access is strictly top-down; the pack omits side access zippers and a lower sleeping bag compartment, meaning retrieving a layer at the bottom often requires a mid-trail yard sale. Additionally, while scraping between two boulders in the backcountry, Tjossem managed to tear the hip belt’s stretchy mesh fabric on a Leatherman (requiring a quick patch repair). The fabric’s 1,000 mm waterproof rating will handle morning dew, but it will not survive a downpour without a separate rain cover.

Should You Buy It? For backpackers seeking a sub-3-pound pack with real aluminum frame structure under the $300 mark, the EXPED Lightning 50 is a fantastic option. Hikers routinely hauling over 35 pounds or seeking maximum plushness should look to packs like the Gregory Paragon 60, but for lightweight weekenders, it delivers exceptional value.

The Mountain Hardwear Kazam 60 ($315) hits a sweet spot in pack design: a high-capacity, sub-3-pound rucksack that refuses to compromise on load-hauling structure. Designed for backpackers who push into multi-sport or shoulder-season territory, it combines weather-resistant fabrics with an aggressive frame system built to carry heavy payloads comfortably.

The Tech: The Kazam carries on a V-shaped aluminum frame that anchors directly into a pivoting hip belt. Unlike typical packs that transfer weight statically, this setup allows the pack body to shift dynamically with your stride, keeping your center of gravity tight without pulling against your shoulders. When Senior Editor Nick Belcaster put this suspension to the test in Washington’s backcountry, he packed the Kazam to its 60-liter collar with a rolled packraft, breakdown paddle, and a full overnight kit totaling nearly 38 pounds. Despite that, the pack stayed balanced where other bags would barrel out.

What We Like: Weather protection and trail accessibility are dialed. The TPU-laminated ripstop body effortlessly shrugged off steady drizzles without requiring a pack cover. Up front, the running-vest-style shoulder harness keeps a Garmin inReach, energy gels, and small electronics within arm’s reach. Belcaster also noted that Mountain Hardwear nailed the compression system; once he launched the raft and reduced internal volume, the bag cinched down flat and carried tightly without extra bulk.

What We Don’t: The design isn’t without a few minor frustrations. The hip belt pockets are cut small, making it a squeeze to fit much of anything inside. Additionally, testing revealed that the sternum straps (which rely on tension to stay connected) have an annoying tendency to pop off for hikers with larger busts.

Should You Buy It? Compared to traditional heavy-haulers, the Kazam 60 offers significantly more mobility, a lower weight, and superior weather resistance. For technical backcountry missions requiring real load-hauling muscle alongside agility on the trail, it is a top contender.

Bottom Line: A feature-rich 60-liter pack with a broad J-zip front entry and an aggressive compression system. It offers a comfortable, ventilated carry for heavy loads, though its 4-pound 7-ounce build and web of straps can feel like overkill.

The REI Co-op Traverse 60 ($269) strikes a good balance between comfort, high capacity, and value. Designed specifically for gear-heavy missions where organization is paramount, it serves as a sturdier, higher-capacity companion to REI’s lighter Flash series.

The Tech: The Traverse rests on REI’s FreeFlow ventilated back panel paired with a thickly padded hip belt. When tester Katie Botwin pushed the pack through long trail days loaded with 35 to 45 pounds, the back panel maintained solid airflow while the hip belt effectively managed pressure points. However, when Botwin rigged splitboards to the exterior compression straps, the extra pull caused the shoulder straps to slide out slightly toward her armpits. Balancing the tension across the pack is important to getting your load to carry just right with the Traverse.

What We Like: Accessibility and versatile organization. Access is available from top, bottom, and front J-zip entry points, making camp setup effortless without having to dig. Botwin loved the multi-divisional pocket layout in the floating top lid, which detaches to double as a standalone daypack. The pack also held up remarkably well when dragged through dense brush, largely thanks to the durable face fabrics and an included rain cover.

What We Don’t: At 4 pounds, 7 ounces, the Traverse 60 is decidedly non-ultralight. The removable lid/daypack design also requires hikers to completely clear out unused gear before taking it on short day trips (unlike packs with dedicated independent daypack sleeves, such as the Mountain Hardwear PCT 55). Additionally, the abundance of external compression straps, ice axe loops, and adjustment buckles can get a bit confusing to adjust.

Should You Buy It? Backpackers who prioritize load support, deep organization, and all-around trail durability over pure weight savings will find huge value in the Traverse 60. It is an ideal pick for longer backcountry treks or shoulder-season trips between towns where carrying extra gear is certain.

Bottom Line: The Flash Air is an accessible gateway into ultralight gear, though non-taped seams and a warm back panel keep it slightly behind specialized competitors.

The REI Co-op Flash Air 50 Pack ($299) takes direct cues from cottage ultralight manufacturers while retaining the familiar accessibility of a mainstream retailer. By stripping out a pound of weight compared to the traditional Flash 55, eliminating the floating lid, and streamlining features, it offers a path for hikers looking to drop significant pack weight without committing to a bare-bones sack.

The Tech: Supported by internal spring steel stays and an hourglass-shaped frame, the Flash Air 50 weighs in at 1 pound, 15 ounces. The pack body utilizes an 87% nylon and 13% polyethylene UHMWPE ripstop fabric, providing serious abrasion resistance over standard nylon. When tester Samuel Martin took the pack on a 23-mile, 4,500-foot vertical circuit through North Carolina’s rugged Linville Gorge Wilderness, carrying an 18-pound loadout, the pre-curved hip belt and padded harness kept weight centered and comfortable across steep climbs and river rock hops. Martin noted the suspension could easily manage 5 to 10 additional pounds beyond its 18-pound test weight, well within its 25-pound rated limit.

What We Like: On-the-trail functionality is well thought out, with dedicated, forward-angled bottle sleeves behind the hip belt that allow easy one-handed access while moving. The main roll-top closure paired with a top Y-strap makes it simple to compress internal space or secure a bulky bear canister externally. The pack also integrates REI’s PackMod system for optional customization, and Martin appreciated that the hip belt pockets easily fit a modern smartphone and daily trail snacks.

What We Don’t: Weather resistance is a limitation (at least compared to true DCF packs); when a torrential downpour hit at the end of Martin’s trek, water made its way into the main compartment through the non-taped seams and hydration port, necessitating an internal trash bag liner. Additionally, while the back panel padding offers more comfort than zero-structure UL bags, it lacks airflow and runs hot during steep ascents. The included Packmod mesh shoulder attachment also hangs a bit awkwardly while hiking.

Should You Buy It? For traditional backpackers transitioning away from heavy workhorses like the Osprey Atmos who want to shave over 2 pounds of pack weight, the Flash Air 50 is an easy recommendation.

How We Tested the Best Backpacking Backpacks

Our backpack testing aims to cover both in-field impressions and bench measurements to provide a comprehensive picture of the product’s performance. Here’s the breakdown on how we rate them.

  1. Field testing: We don’t render a verdict until a pack has survived a full season. Our team of thru-hikers and mountain guides rucked these packs across the abrasive granite of the High Sierra, the humid thickets of the Appalachians, and the unpredictable rain of the Pacific Northwest. We look for wear and tear, how a foam hip belt compresses over time, or how a zipper tracks after being coated in trail dust for a month.
  2. In-house ping-pong protocol (volume testing): To ground-truth manufacturer claims, we utilize thousands of ping-pong balls to replicate ASTM volume tests. This allows us to measure the actual usable space in the main compartment versus the bonus volume in the mesh pockets. We also perform a Bear Canister Fit test, ensuring a standard BV500 fits vertically and horizontally without creating a painful bulge in the back panel.
  3. The overload sag test: We intentionally load every pack to 15% past its manufacturer-recommended limit and hike a 5-mile loop with 1,500 feet of vertical gain. We measure frame sagging and monitor for squeaking or hardware failure under duress. If a heavy-hauler can’t handle a 55-pound water carry without the hip belt slipping, it loses points.
  4. The bushwhack abrasion trial: Modern technical fabrics like Ultra 200X and UHMWPE claim to be indestructible, so we verify it. We take these packs off-trail into dense scrub oak and blackberry brambles, and see how vulnerable areas such as bottle pockets and pack bottoms fare in the long run.
  5. Our backpack rating system: We take all of our in-field and bench testing feedback and use it to rate each backpack on a set of four essential metrics:
    • Comfort: 30% weighted. A 10/10 means the pack disappears on your back at 45 pounds. We look for zero hip belt slippage, no shoulder pinch, and a suspension that pivots with your natural stride.
    • Volume & Organization: 30% weighted. A 10/10 allows you to reach a stove at the bottom of the bag without a full pack explosion. We reward dual-access side pockets and reach-around water bottle holsters.
    • Weight: 20% weighted. A 10/10 requires a total weight under 3 pounds for a fully framed 60L pack. We penalize heavy-haulers that exceed 5.5 pounds unless they provide an objective increase in support.
    • Durability: 20% weighted. A 10/10 requires 400D+ high-tenacity nylon or technical Ultra/DCF fabrics. The bottom must be reinforced to survive being dropped on sharp talus repeatedly without a puncture.

Our Expert Testers

The GearJunkie team comprises a diverse group of backpackers. From weekend warriors to seasoned thru-hikers, we’ve collectively spent many years on the trail.

Senior Editor Nick Belcaster leads our backpack testing efforts. Also a veteran of the Pacific Crest Trail, he’s racked up many trail miles since, and worked his way through a not small number of backpacks in the process — hiking long trails from Iceland to Alaska and Patagonia. His pack needs range from carrying ultralight load-outs to an entire packraft and 8 days of food, and he leads our current bench testing program.

Tester Chris Carter has also made significant contributions to this guide. He has extensive experience putting various backpacks through torture and torment, having thru-hiked the Triple Crown of long trails in America: the Pacific Crest Trail, the Continental Divide Trail, and the Appalachian Trail. He’s navigated the sinking sadness of a mid-hike pack failure and knows the importance of choosing a model that fits your needs and will last the distance.

Staff writer Austin Beck-Doss has clocked countless miles under the weight of bulging backpacks. A prolific rock climber, hiker, and all-around outdoorsman, he knows the value of a cozy pack for schlepping heinous loads to the far-flung corners of the world. He led the charge with this guide, accruing our initial selection of nine packs in May 2021. Additionally, tester Bergen Tjossem (a conservation professional and Colorado resident) assisted in our pack testing last summer.

Our Testing Process & Testing Grounds

This list of product recommendations above results from thorough field testing. When testing packs, we pay careful attention to ease of use, long-term durability, comfort, and overall value. Impressive-sounding features might look good on paper, but they don’t always translate to actual performance.

Our testing has taken us pretty far. From the Huemel Trek in Argentina to off-trail bushwhacks deep in the Brooks Range, our team goes deep while testing these backpacks, aiming to get some serious trail miles on them before rendering our verdict. When out in the field, we’re looking at a few specific metrics: maximum comfortable weight, gear organization, suspension adjustability, and durability.

Beyond the field, we also dig into the nitty-gritty and conduct a series of bench tests. These include standard measurements such as pack weight and checking fit on several different body types, as well as our in-house volume testing, where we utilize ping-pong balls to confirm the volumes of these backpacks. Ground-truthing information like this allows us to stack packs head-to-head and cut through marketing claims.

Buyer’s Guide: How to Choose a Backpacking Pack

Purchasing a backpack — especially for the first time — can be challenging. Reliable gear is the foundation of a successful backpacking trip, and a good pack may be the most important item in your whole kit.

The ideal pack should feel balanced and comfortable while hiking. In camp, a well-designed pack helps keep your systems organized and efficient.

In this how-to-choose guide, I will discuss all the important considerations that will help you choose the right pack. Everything from padding and water protection to sizing and capacity is explained in detail. By the end, I hope that you’ll feel confident about choosing the perfect pack to support your backpacking adventures.

What Backpack Is Right for Me?

I’ve dug deep into backpacking packs in this guide, but there are a number of other pack designs out there that may potentially fit your needs better. Check out our Best Ultralight Backpacks Guide if you’re really trying to cut weight and carry less on your back, or our Best Daypacks Guide if your trips into the woods are often confined by 24 hours.

What Size Backpacking Pack Do You Need?

Choosing a pack volume isn’t just about the length of your trip, it’s about the bulk and displacement of your specific kit. A 50-liter pack might feel overwhelming for a minimalist but claustrophobic for a winter explorer. To avoid frustration, I recommend performing a volume displacement test before you buy.

  • How to Calculate Your Pack Volume: This method bridges the gap between manufacturer specs and your real-world gear. Gather your Big Three kit (tent, sleeping system, and pad) along with your stove, filtration, and layers. Place everything into a cardboard box, compressing them as you go. Measure the length, width, and depth of the occupied space in inches, multiply them, and divide the total by 61.02 to convert to liters. Always add roughly 10 liters to this final number to account for food, fuel, and a bear canister.

Backpacking Pack Size Ranges:

  • Minimalist Packs (35–45 Liters): To successfully use a sub-45L pack, your kit must be compressible and low-bulk. These packs are ideal for thru-hikers and fast-packers who prioritize speed and agility. However, this volume leaves zero margin for overpacking. If your gear isn’t dialed in, you’ll find yourself struggling to close them. The Hyperlite Mountain Gear Southwest 40 remains one of my top recommendations here, as its DCF construction offers the weather resistance and durability that long-distance hikers demand.
  • The Standard Range (50–70 Liters): This volume serves the majority of weekend warriors and 3-to-5 day explorers. It provides enough room for synthetic sleeping bags, extra layers, or even a luxury item like a backpacking chair. When loading a pack of this size, always keep the 20% Rule in mind: for optimal safety and comfort, your total pack weight should not exceed 20% of your body weight. For those seeking a balance of weight and support, the Gregory Paragon 58 (and women’s Maven 60) are prime examples of packs that offer enough suspension to make a 35-pound load feel significantly lighter.
  • For Heavy-Hauling (70–90+ Liters): When your adventures require specialized equipment, you move into the realm of the load haulers. These packs are designed with overbuilt suspension systems and reinforced frames to prevent the pack from sagging under the weight of gear-intensive trips. The Gregory Baltoro 100 Pro is the pack I lean on most frequently when the scales will tip past 50 pounds, as its pivoting hip belt manages heavy weight without bruising the iliac crest.

Dialing in the Fit: Measuring Your Torso & Hips

A backpacking pack suspension system isn’t worth much if the frame doesn’t match your body. Because torso length can vary between two people of the same height, selecting a pack size based on “tall” or “short” is a mistake. To ensure the load transfers to your legs rather than crushing your shoulders, you need to measure two specific metrics: your Torso Length and your Iliac Crest (Waist) Circumference.

The Torso Length Test

This is the most critical factor for pack sizing. If the torso is too long, the pack will pull away from your shoulders. Too short, and it will put 100% of the weight on your trapezius muscles.

  • The Measurement: Tilt your chin to your chest and have a friend locate the C7 vertebra, the prominent bone protruding at the base of your neck. Measure from that point down your spine to the center point of your back (the spot level with the top of your hip bones).
  • The Result: Most adults fall between 15 and 22 inches. If you’re between sizes, I generally recommend sizing down for a more secure fit, provided the load lifters still maintain a proper 45-degree angle.

The 80/20 Rule: Proper Hip Belt Sizing

While your torso determines the frame size, your waist measurement determines the hip belt. For optimal comfort, 80% of the pack’s weight should be carried by your hips.

To find your size, wrap a tape measure around the highest point of your hip bones (the iliac crest) rather than your natural waistline. The padded center of the belt should sit directly atop these bones. If you have a mismatched build (such as a long torso and a narrow waist), look for brands like Gregory or Osprey that offer interchangeable hip belts.

Tester’s Tip: “Never trust the fit of an empty pack. I always recommend testing a bag with at least 25 pounds of weight, as an empty frame can easily mask a torso that is too long or a belt that fails to cinch tight enough.” — Lead Gear Tester Nick Belcaster

Backpack Suspension Components

While a pack may look like a simple bag from the outside, the frame and suspension work in tandem to carry all of your gear, food, and water. Understanding these parts allows you to troubleshoot discomfort on the trail and properly adjust your pack as your pack’s weight changes along the trip.

  • The Internal Frame & Framesheet: The frame is the backbone of your pack. Most modern packs utilize an aluminum hoop or dual stays to provide rigidity. This structure prevents the pack from barreling when stuffed full and ensures the weight is transferred directly down to the hip belt. In lighter packs, you may find a framesheet (a thin plastic or carbon fiber panel) which provides a barrier between your gear and your back while offering just enough structure for medium loads.
  • The Hip Belt & Lumbar Pad: The hip belt is the most critical component for long-term comfort. Its job is to wrap firmly around your iliac crest, allowing your legs to carry the load.
    • The Lumbar Pad: This is the cushioned area at the base of the spine. A well-designed lumbar pad prevents the pack from sliding down and helps maintain the natural curve of your back.
    • Dual-Pull Buckles: Look for hip belts that pull inward toward the center; this mechanical advantage makes it significantly easier to get the belt tight enough to stay in place.
  • Shoulder Harness & Sternum Strap: The shoulder straps should follow the contour of your chest and shoulders without gapping or pinching. Their primary role is to keep the pack from falling backward, rather than lifting the weight.
    • The Sternum Strap: This small strap connects the two shoulder pads across your chest. It prevents the shoulder straps from sliding outward toward your armpits and helps stabilize the load on uneven ground.
  • Load Lifter Straps: When pulled to a 45-degree angle, load lifters pull the top of the pack toward your spine. This shifts the center of gravity closer to your body, instantly relieving the pulling sensation on your shoulders and making the load feel lighter and more integrated with your movement.

Backpack Organization & Access

A backpack’s layout dictates your trail efficiency, or how quickly you can find your rain shell when a storm breaks or access a snack without dropping your pack. Organization styles generally fall into two camps: Minimalist and Feature-Rich.

Primary Closure Systems

The way a pack closes at the top affects its weather resistance and volume flexibility.

  • Top-Lid (The Brain): This is the traditional design featuring a large cinched opening covered by a zippered compartment. It provides immediate access to small essentials (headlamps, maps) and acts as a compression flap for stowing a climbing rope or foam pad underneath.
  • Rolltop Closure: Adopted from dry-bag technology and seen on packs like the Hyperlite Mountain Gear Southwest, this design is now the standard for ultralight trekking. These designs allow for variable volume. As you consume food over a 5-day stretch, you can roll the top down further to keep the load compact and stable. It also offers superior water resistance compared to traditional lids.

Main Compartment & Access Points

While most packs are top-loaders, certain models include secondary entry points to prevent gear explosions at camp.

  • Top Access Only: Common in ultralight packs to save weight. This requires a disciplined packing strategy (e.g., sleeping bag at the bottom, snacks at the top).
  • Peripheral Zippers (Front/Side/Bottom): Found on heavy-haulers like the Osprey Aether, J-shaped or U-shaped zippers allow you to pull a stove or puffy jacket from the bottom of your pack without removing everything above it.

External Storage & Pockets

  • Hip Belt Pockets: These are essential for on-the-go items like lip balm, GPS units, or calories. Pro Tip: Look for overbuilt zippers here, as these pockets take the most abuse from sweat and abrasion.
  • Hydration Sleeves: Most modern packs include an internal sleeve and port for a water bladder. If you prefer bottles, prioritize side pockets with a forward-leaning cutout so you can grab your water without dislocating a shoulder.

Compression Straps: Stability vs. Lashing

Compression straps are often misunderstood as mere gear loops, but their primary function is load stabilization.

  • On Frameless Packs: Without a rigid structure, these straps serve mostly as lash points for trekking poles, tent poles, or wet rain flies.
  • On Framed Packs: These straps pull the load closer to the internal stay, shifting the center of gravity toward your spine. This prevents the pack from swaying, which is the leading cause of lower back fatigue.

Rain Protection

Keeping your gear dry is a non-negotiable safety priority. Moisture doesn’t just add weight; it can lead to dangerous heat loss if your insulation (sleeping bag and layers) gets soaked. To combat this, hikers generally choose between External Protection and Internal Protection.

External Protection: Rain Covers

A rain cover is a form-fitting waterproof shield, typically made of silnylon or polyester, that cinches over the pack’s exterior.

  • Integrated vs. Aftermarket: Some packs, like those from Gregory or Osprey, include a dedicated pocket (usually on the bottom) housing a built-in cover.
  • The Trade-off: While effective against vertical rain, covers leave the back panel exposed. In heavy storms, water can seep down your back and pool at the bottom of the pack. They are also prone to snagging on branches during off-trail travel or blowing away in high winds.

Internal Protection: Pack Liners

Many experienced thru-hikers have moved away from rain covers in favor of internal liners. This method involves lining the entire main compartment with a waterproof bag before packing your gear.

  • The Benefit: This is the most reliable way to ensure your Big Three stays dry. Because the protection is inside, you don’t have to stop and scramble to fix a cover when a flash storm hits, as your gear is already shielded.
  • Types of Liners:
    • Nylofume Bags: Transparent, odor-resistant, and incredibly lightweight. These are the pro’s choice for long-distance hiking because they don’t tear as easily as standard plastic.
    • Polyethylene Bags: Often sold by brands like Gossamer Gear, these are tougher than a standard trash bag and specifically sized to fit backpacking volumes.
    • The Contractor Bag Hack: A heavy-duty, 3-mil contractor trash bag is the cheapest, most durable budget option, though it lacks the transparency and custom fit of technical liners.

What Are Modern Packs Made From?

The modern backpack market is a battle between tensile strength, abrasion resistance, and weight. To understand a pack’s longevity, you must look past the brand name and evaluate the technical composition of the textiles.

Traditional Nylon & Ripstop

Most legacy packs utilize high-tenacity nylon treated with a Durable Water Repellent (DWR) coating.

  • Denier (D) Explained: This measurement indicates the fiber thickness. A 210D nylon is standard for lightweight packs, whereas bombproof models like the Mountain Hardwear AMG 75 utilize 840-denier nylons and Ultra 400X accents.
  • The Benefit: High-denier nylon is incredibly affordable and excels in sliding abrasion (dragging a pack over granite).
  • The Trade-off: Nylon is hydrophilic (it absorbs water weight) and will eventually wet out regardless of the coating.

Technical Laminates: Dyneema & Ultra

High-end and ultralight (UL) packs have shifted toward high-tech fabrics that laminate a face fabric to a waterproof film.

  • Dyneema Composite Fabric (DCF): Used by Hyperlite Mountain Gear, this is a non-woven laminate. It is 100% waterproof and has a high strength-to-weight ratio but can be prone to pinhole punctures over time.
  • Ultra (UHMWPE): The current industry standard, Ultra weaves Ultra-High Molecular Weight Polyethylene with high-tenacity polyester.
    • Expert Insight: Contrary to the original text, modern Ultra200 and Ultra400 fabrics are actually more abrasion-resistant than many heavy nylons. They do not need to be babied; in fact, they are preferred for off-trail bushwhacking because they do not absorb moisture or stretch when wet.

Spectra & Gridstops

  • A middle ground between nylon and full laminates, Gridstops (like 210-denier HDPE Gridstop) use a nylon base reinforced with a white spiderweb of Spectra or Dyneema threads. If the nylon base tears, the high-strength grid stops the rip from spreading. This is the most cost-effective way to get UL performance without the $400+ price tag of full laminates.

Price & Value

Backpacking packs vary in price and value. High-quality options range from around $200 to well over $500. More expensive packs may include higher-quality materials or extra features, but sometimes, simpler is better when weight is the biggest concern.

Budget

You’ll typically pay between $150 and $250 for a budget backpacking pack, and while you’re likely to get fewer features, these packs can still do some serious work. The REI Co-op Trailmade 60 ($189) is widely adjustable to a number of body types, and while there are scant bits of flash, its 60 liters of capacity will carry our overnight kit and then some.

Mid-Tier

Spending a little bit more on your backpacking pack will net you not only a few more features, but also undoubtedly some comfort and adjustability, too. The $260 you’ll pay for the Osprey Exos & Eja 58 is common in this range, and for the money, you’ll get into a nicer suspended back panel frame and enough pockets and lash points to secure dang near anything.

Premium

Spending north of $350 on a pack means it’ll leave little on the table, or you’re chasing ounces and after an ultralight pack. The Hyperlite Mountain Gear Southwest 55 ($399) is certainly in the latter camp, and weighs in at an impressive 1 pound 15 ounces. The Dyneema Composite Fabric used on this pack is the reason for the price, but if you’re headed out on a thru-hike, we think it’s worth it.

The ULA Circuit Ultra ($380), on the other hand, uses another cutting-edge textile, Ultra 400, and gains durability for it. Here, too, the material is the main driver of price, but you’re also paying a bit of a premium for going with a cottage industry brand. The attention to detail is unmatched, in our opinion, so it’s well worth it.

Frequently Asked Questions

What is the best backpacking backpack?

The best backpacking pack is ultimately the one that fits your unique body shape and aligns with your trail objectives. Because comfort is paramount when logging high-mileage days, you should prioritize a pack that matches your exact torso length, waist size, and expected gear volume.

For a versatile option that suits most hikers, our top choice is the Gregory Paragon 60 (and women’s Maven 58). This series hits the ideal sweet spot, offering a lightweight design paired with a heavy-duty suspension system that comfortably stabilizes loads up to 50 pounds.

However, the right pack depends on your specific hiking style. If you want a lightweight, budget-friendly option, the REI Co-op Flash 55 offers an approachable price point and a modular design that sheds weight. For hot climates, the Osprey Exos and Eja 58 use a suspended trampoline-style mesh back panel for unmatched breathability. Finally, long-distance hikers looking to cut weight without sacrificing durability will favor the Hyperlite Mountain Gear Southwest 55, which utilizes tough, weather-resistant materials built for the long haul.

We recommend measuring your torso carefully and trying on a few options fully loaded to find your perfect fit.

What is a good-sized backpacking backpack?

The ideal size of your pack depends on your own dimensions, as well as on the amount of gear that you plan to carry. For trips up to 3 days, a 50-70L pack is usually enough. For longer trips, look for a pack that can carry at least 60L.

Is a 40L backpack big enough for backpacking?

Some backpackers have truly mastered the art of thinning down their kit to the bare essentials. However, for most people, a 40L pack will not be large enough for trips longer than a single overnight excursion.

How should I pack my backpack?

Packing your backpack properly will help you maximize its capacity and ensure that you feel balanced while hiking with a heavy load. The more organized your initial packing process is, the less you will have to rummage around looking for stuff during your trip. Knowing how to pack properly and efficiently is an essential part of a successful adventure.

Generally, you’ll want to pack items that you won’t need while hiking near the bottom of your pack. This includes your sleeping bag and extra clothes. The middle of your pack is where you should keep heavier items like food and water. The closer the heavy items are to your back, the better.

Keep frequently used items like rain layers and toiletries near the top of your pack where they will be easily accessible. In your hip strap and top lid, you’ll want to keep things like maps, lip balm, a GPS device, etc.
