Ultralight backpacking is exploding in popularity. With casual backpackers and seasoned thru-hikers alike focusing more and more on a lighter base weight, the options for a streamlined, ultralight setup on trail have expanded dramatically.

There isn’t one blueprint for what makes a perfect ultralight pack, and it really does depend on what you’re comfortable with. To help narrow down the choices, we interviewed a number of knowledgeable thru-hikers and put countless models to the test to find the best ultralight backpacks out there. Ultralight hiking isn’t for everyone, but if you’re looking to pack light or take on extensive mileage by foot, you’ve come to the right place.

Our team collectively tested legions of these glorified tubes for the creation of this guide, with current author Chris Carter having put over 10 different models through grueling tests in the past year alone. An alumnus of the Triple Crown trails in the United States, he’s worn a seemingly permanent groove in his shoulders from schlepping ultralight backpacks across the country — and won’t settle for just any ol’ vessel. He knows the importance of balancing durability, weight, and functionality when scoping out the best ultralight backpack for your journey, and allowed only the crème de la crème into this roundup.

While there isn’t a single ultralight backpack for everyone, we’ve noted some of the useful features and specs of each of our recommendations to help you find the best ultralight backpack for your needs. At the end of our list, be sure to check out our comparison chart, buyer’s guide, and frequently asked questions.

Editor’s Note: We updated our Ultralight Backpacks guide on March 21, 2024, to add the new Black Diamond Betalight 45 — a pack hewn from the newest ultralight and ultratough textile on the block: Challenge ULTRA fabric.

How We Tested Ultralight Backpacks

The GearJunkie team ranges from casual weekend backpackers to full-blown thru-hiking dirtbags and has put thousands of hard-earned miles on a variety of different ultralight backpacks in a range of conditions and landscapes. We know what it’s like to get to the end of the day with a sore back from a poorly fitting or overloaded pack. We’ve therefore tried to whittle this list down to the absolute best models that won’t weigh you down, but also offer a comfortable ride over big-mile days.

Editorial Director Sean McCoy led the charge with this guide back in November 2020, curating our initial selection of nine packs. A life-long hunter, backpacker, and all-around outdoorsman, Sean knows the importance of balancing weight with function on ultralight objectives in the backcountry.

Senior Editor Chris Carter took over this guide in August 2022 and has been combing online catalogs, attending backpacking gear shows, and consulting his Rolodex of seasoned thru-hiking dirtbags to bring you the streamlined selection of 15 worthy packs you see today. Chris has significant experience putting various ultralight backpacks through torture and torment, having thru-hiked the Triple Crown of long trails in the United States, and continues to backpack around the world. 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.

Every gram counts when trying to pare down your base weight. So, while testing these packs, we considered factors such as durability, value, useability, and functionality of each accessory and feature to determine the quality of the pack. After weeks of putting each model through the wringer on fast and light backpacking trips, we feel confident recommending each of these backpacks to those wishing to push the limit and lighten their load on long trails.

Buyer’s Guide: How to Choose the Best Ultralight Backpack

We’ve all had that moment of frustration as new backpackers where we realize we’ve overpacked, and contemplate chucking half the gear we brought off the next overlook.

It’s the top of the first climb of the day, sweat is pouring off you, your shoulders want to kill you, and suddenly that 5-pound tent you thought would be essential starts sounding a lot less awesome. You get home, saw your toothbrush in half, and start to research.

If you’ve decided to pull the plug and join the ultralight cult, there are some things you need to consider. First, it has to be done carefully as you are still headed into the backcountry with this kit, and need to be prepared for all the unexpected twists and misadventures mother nature loves to throw our way.

Don’t focus too much on going lightweight that you sacrifice essential elements of safety in the wild, or bring a setup that is going to fall apart after 2 days on trail.

A reliable ultralight kit starts with a functional, solid backpack. With so many options on the market, it can be hard to decide what to go with, and you should think about the elements that you will encounter on your trip, and the level of comfort you want, before making a decision. Below we’ve broken down several factors to consider when choosing the best ultralight backpack for your adventure, which hopefully streamlines the process.

Ultralight Backpacks Fabric Selection and Weather Resistance

Ultralight backpack manufacturers have the difficult challenge of offering an extremely lightweight package while also being durable enough to hold up to months of abuse on rough trails through bad weather. For that reason, these packs are constructed with the latest, most durable materials on the market, which often explains the high price tag.

Some of the most common fabrics found in ultralight packs are Dyneema Composite Fabric (DCF), Ultra, ECOPAK, X-PAC, and nylon (such as Robic or CORDURA). Each of these fabrics has different benefits and uses, which impact the weight, durability, and weather resistance of the packs they construct.

Many people look at ultralight packs and think they are waterproof, since they often resemble the classic roll-top closures of dry bags, or are made with shiny reflective material. While the fabric of some of these packs is highly water-resistant, you will still want to add additional rain protection to your gear for when the weather turns foul.

Dyneema Composite Fabric Construction of Ultralight Backpack

Our testers like to use separate ultralight Dyneema dry bags for contents that absolutely need to stay dry (such as electronics, a first aid kit, a puffy jacket, and a down sleeping bag), with a large lightweight pack liner that always stays in the backpack, protecting everything. The two most popular waterproof pack liners are Nylofume bags, such as this one sold by Gossamer Gear.

We’ve found this to be the best, lightest, and cheapest, way to ensure that your gear stays completely dry. And you don’t have to waste time desperately fitting a rain cover over your pack as a freak storm sweeps in, as the inside contents are already protected. Just make sure there’s nothing too important in the external shove-it pocket.

In general, Ultra, ECOPAK, DCF, and X-PAC are waterproof to some degree, though the packs that use them may not be seam-taped, and water will seep through in prolonged bad weather. Most hikers who use these packs will still use a pack liner or cover in significant rain to keep their gear dry. Materials such as Robic nylon, on the other hand, will absorb water slowly over time and allow your pack contents to get wet.

Ultralight Backpack Volume Selection
Ultralight packs vary in the materials they use, but most are designed with durability in mind for the long run; (photo/Honey McNaughton)

The introduction of DCF and X-PAC to the backpacking scene represented a pretty significant jump in ultralight fabric technology due to their incredible strength-to-weight ratio. Packs such as the Zpacks Arc Blast have secured their spots as the lightest packs in their size range because of DCF, with the ability to carry loads of up to 35 pounds while maintaining an impressive, ultralight weight.

Ultralight Backpack Volume Selection

The volume of your ultralight pack is an important part of the selection process, and depends heavily on how dialed in your base weight is. Ideally, you want to have a sub-10-pound base weight while wearing ultralight packs, which includes everything aside from consumables (such as food, fuel, and water).

This is largely because, in order to achieve such a low weight, ultralight backpacks are generally not as durable or supportive as traditional, heavier backpacking backpacks.

It’s important to consider if the volume of the pack you choose will support the goals of your trip; (photo/Honey McNaughton)

Overpacking them will result in faster deterioration over time, and they just won’t hold the load as comfortably on your back. For that reason, you want to make sure the gear you are packing is also as ultralight as possible if you are going to be using an ultralight pack.

For most ultralight hikers, a 40 L pack will provide enough volume for a long weekend trip, or a 3- to 5-day push between towns on a thru-hike. This will always depend on the climate and terrain you intend to hike through, but for general three-season use, 35 L to 40 L should suffice. Some packs, like Hyperlight’s Windrider 55 can expand or contract a good deal to accommodate different volumes of loads.

As hikers obsess further over every gram in their packs, truly committed ultralight backpackers can whittle their entire thru-hiking kit to fit into 30L or smaller packs, but this comes with some notable sacrifices.

Using simple tarp shelters (or even a rain poncho) in lieu of tents, going stoveless, or carrying less food helps to save weight, but not everyone is ready to take that leap.

Hip belts on Ultralight Backpacks

Ultralight Backpacks can be Carried With or Without a Hipbelt

For a couple of reasons, many ultralight backpacks have a removable hip belt or no hip belt at all (such as LiteAF’s Ultra 30L, which have optional hip belt additions). This is primarily found in frameless ultralight packs. Many hikers who have already dialed their base weight well below 10 pounds find that they can save even more weight by leaving the hip belt off, without sacrificing too much comfort.

With frameless ultralight packs, hip belts are not as load-bearing as traditional packs, as there is no frame for the load to be transferred to. The hip belt really only helps keep the pack close to your body while hiking, preventing it from jostling around, since you optimally will be carrying a weight that won’t overly fatigue your shoulders.

While most ultralight packs will still have a hip belt, they will often not be as padded as traditional packs (such as the hip belt on Mountain Laurel Designs’ Exodus 55L), and you may have the option of removing them entirely. You can still find great ultralight options, such as the Granite Gear Crown3, that have solid suspension, ventilation, and support at the cost of a slightly heavier package.

It’s important to think about the comfort level you are looking for in your pack, and how far you are willing to go to cut more weight.

Packing an Ultralight Backpack

As you would with traditional backpacks, keep weight distribution in mind as you load up an ultralight backpack each morning; (photo/Chris Carter)

You want to pack an ultralight backpack in much the same way that you would pack a traditional backpack, however, there are some additional considerations that are important to note. Namely, ultralight packs cannot carry the same weight that traditional packs can, so it is important to have as minimal and lightweight a kit as possible. This will not only prolong the life of your ultralight backpack but will make it feel a lot more comfortable over the long haul.

As previously mentioned, you will ideally have a base weight that is under 10 pounds. Starting at the bottom of your pack, place your lighter, fluffier items like a sleeping bag and other elements of your sleep kit. These will serve as a “pillow” on your lumbar on top of which some of your heavier items can sit.

Bulkier, heavier items such as your cooking kit, food, and tent, should go in the middle of the pack and be situated as close to your back as possible. By putting these items in the middle of your back, you alleviate a significant amount of stress from your shoulders or lower back, which is particularly important with ultralight backpacks.

Ultralight Backpacks

Finally, at the top of your bag, you want to pack lighter items that you may need to use throughout the day, such as a midlayer or rain jacket.

Since ultralight backpacks also tend to have less padding than other packs, you want to be more aware of how your gear is fitting inside your pack, in order to avoid things poking uncomfortably into your back.

When packing more featured, framed models — like Osprey’s cushy Exos Pro 55 — you don’t have to be quite as careful, as the load isn’t jutting directly into your back. Most ultralight backpacks force you to think carefully about how your gear meshes in the pack, so it doesn’t sit uncomfortably against you, but this isn’t as big of a consideration when the frame separates the load from your back.

These framed models also allow you to carry heavier loads, since more of the weight is transferred to your hips through the rigid structure of the frame. Additionally, compression straps work much better on framed backpacks than frameless ones, as there is built-in structure to compress the load against. This means you can often achieve a tighter, less wobbly package while bounding along the trail with framed packs.

Value

Getting ultralight gear in the mail can sometimes be a disconcerting experience. You just dropped $300 on this package and you can barely feel it in your hands!

While it may seem flimsy and fragile, most ultralight backpacks on the market are constructed with the leading ultralight and ultradurable materials out there and can take quite a beating. There are some elements to consider, however, when choosing the right pack for you.

Durability and Longevity Concerns with Ultralight Backpacks

If going as light and fast as possible is your biggest concern, and you have the budget to be able to replace gear as it deteriorates, choosing an ultralight pack purely for its weight could be a good option. If you want an ultralight option, but also plan on putting it through a little more torture and want some comfort along the way, you might want to look at a more durable, slightly heavier model.

Buying an ultralight pack is an investment that has the potential to greatly improve your backpacking experience. The ability to travel light and fast not only increases the amount of wilderness you can enjoy in a given time but can also reduce the beating your body takes on a demanding backpacking trip, allowing you to hike further and limit injuries.

Ultralight Backpacks: Pros & Cons

The Good

Ultralight backpacking means keeping your entire load low. Your base weight, including all your gear — except consumables like food, water, and fuel — should be under 10 pounds.

And that’s where these packs shine. They are light themselves, thus adding very little weight to your back, but they also carry light loads comfortably and can stand up to reasonable on-trail use.

The Bad

You really need to keep your weight down with these packs (Stone Glacier Terminus excluded). Most of them won’t serve you well if you load them heavy, so they’re a little less versatile than more robust backpacks.

Where does this matter? If you own just one backpack and plan to use it for hiking, ski mountaineering, and rock climbing, you’ll want to look elsewhere.

Also, some of these packs aren’t super durable for off-trail hiking, so be sure to scrutinize materials closely if you plan to use them while bushwhacking.

Ultimately, you will have to decide if you’re willing to trade creature comforts for minimal weight. For those who’ve made the leap, the above are some of the best ultralight backpacks on the market.

FAQ

What is the best ultralight backpack?

Ask 100 hikers about their favorite ultralight pack and you’ll get a dozen different answers. But like all backpacks, the most important aspect is that it fits your body perfectly and is adjusted properly! If you don’t know how to fit a pack, it’s worth a trip to an outdoor shop to talk with a qualified salesperson.

Are ultralight backpacks worth it?

If you can keep your packing weight low, yes, an ultralight backpack is worth the investment for many hikers. However, it’s worth noting that ultralight packs require the user to understand how to pack efficiently to keep their load weight quite low, usually less than 25-30 pounds.

If you expect your gear will weigh more than that, an ultralight backpack will probably not be a good choice, as many won’t support heavy loads very well.

What is a good base weight for ultralight backpacking?

Your base weight is the weight of all your gear not counting things you consume such as water and food. So it includes things like your stove but does not include the food you cook.

Most ultralight backpackers consider a base weight of 10 pounds to be a good measure of ultralight backpacking. Get it down to 5 pounds, and you’re in the superlight backpacking range. For more casual, lightweight backpacking, you can stretch the weight up to about 20 pounds.
