The Best Backpack Coolers of 2026

The Engel Roll-Top High Performance Backpack Cooler ($190) is a true powerhouse in the world of backpack coolers. Weighing in at just over 3 pounds, this midweight cooler is one of the most robust and durable options we’ve used. We put the Engel to the ultimate test during a week-long archery hunting trip in the Colorado Rockies. The pack endured the rigors of being tossed around the back of an ATV, faced the demands of elk camp life, and generally took a beating — yet it came home looking as good as new (after a thorough hose down). 

Constructed with 840-denier material, this Roll-Top offers strength and abrasion resistance. The exterior is fortified with laminated thermal plastic urethane (TPU) film, which provides an extra layer of puncture protection — it didn’t even get a scratch while off-roading.

While there’s a 1-inch layer of closed-cell foam insulation and welded seams, which helped keep our food cold, the unique design also has a patent-pending vacuum valve that allows you to attach your at-home vacuum hose to suck out air. This step removes any trapped air between the foam and the TPU, enhancing insulation and improving thermal efficiency.

When we packed the Engel on its side for the bumpy drive out, we were pleasantly surprised that the roll-top closure and secure clips kept everything contained. Despite hours of navigating a rough, muddy 4×4 road, we experienced zero leaks. We also found a new appreciation for the rectangle shape as it stacks nicely with our plastic bins. 

Out in the field, the padded back and shoulder straps are surprisingly comfortable. The adjustable chest strap has a wide enough range for various heights and chest sizes. When we filled it with items too heavy to wear on our back, the side handles came in handy for two people to carry together. 

A third grab handle above the back panel is equally sized and easy to wrap our hands around. Between the long ice retention, roomy compartment space, and overall ruggedness, the Roll-Top High Performance Backpack Cooler has proven to be a solid choice for our outdoor adventures. 

The Coleman XPAND 30-Can Soft Cooler Backpack ($49) makes hauling cold drinks and snacks easy and comfortable. It’s a functional soft cooler with a plush, malleable back panel, moderate insulation, and thoughtful features that support active, all-day use. Plus, the price doesn’t hammer the bank account. 

This budget-friendly backpack was easy for tester Dane Tudor to pull on and off when e-mountain biking from the RED Mountain Ski Resort base to the excavators during 5 months of bike park construction. Tudor’s priority was hands-off carry for a two-in-one cooler and pack, and this Coleman checks that box. The XPAND worked in a wide temperature range of 65 to 100 degrees Fahrenheit.

Padded shoulder straps and a wide top handle make it easy to carry, and even when fully loaded, it sits comfortably on your back. Inside, there’s room for up to 30 cans, and insulation keeps contents cold for up to 2.5 days in shady conditions hovering around 75 degrees. Our test results mirrored the brand’s claim.

While this pack doesn’t deliver premium cooling power, we appreciated the details. A front bungee expands to stash a hoodie or rain jacket. The 4-way stretch side mesh pocket easily fits our large water bottle. The mesh pocket inside the lid has excellent potential for space savings, but without a zipper, our utensils fall into the pack, and we’re concerned that forks can gash the soft interior.

The front unzips to offer up a large zippered mesh pocket for essentials like keys or earplugs. Inside there’s a clip, a slender pocket for receipts, and a roomy pouch for stashing basic first aid items. 

The fairly durable material on the base meant we could set the cooler down on dirt while digging trails with the machine, but the base lacks rigidity, so the pack could topple over on uneven ground. If you’re willing to pay a bit more, the Titan by Arctic Zone 24 Can Backpack Cooler is another excellent value pack with more impressive ice retention than the XPAND and five pockets, including two mesh side pockets for water bottles. 

If your priority isn’t premium ice retention or a rigid foundation, this Coleman cooler pack is a solid choice for everyday utility, from the job site to outdoor trips. 

With plenty of comfort and space for cutlery or seasoning, the Titan by Arctic Zone 24 Can Backpack Cooler ($45) is an excellent value pack with impressive ice retention. And we appreciated the large variety of pockets — five in total plus a front bungee cord system — for storing essentials. Water bottles securely fit in the mesh side pockets, while we stashed keys and a blister kit in the top zippered pocket.

The side pouches are so wide they can easily fit a water bottle plus two big bottles of sunscreen with room to spare. The front pocket was perfect for carrying out trash. And there was even space to tuck a windbreaker into the bungee webbing on the front of the pack. Pockets galore!

One of our most memorable tests with this cooler was while working at an ultramarathon in the Sawatch mountain range of Colorado over a hot July weekend. After pre-cooling the main cooler space, we found the Ice Walls to be impressive and hold a consistently cool temperature for an entire weekend. We liked having separate ice pack compartments that kept condensation off food.

While we wouldn’t recommend this bag for extended hikes, this cooler outperformed its price point for an extended weekend of variable temps: in and out of the car and hanging around outside. And according to our controlled test, the Deep Freeze retained ice for 80 hours.

During another 100-mile ultrarunning race in Montana’s sweltering Crazy Mountains, we hiked with this cooler for more than 10 miles to support athletes. Ultimately, while it performed well and the padded shoulder straps were comfortable, the system lacked customization. Namely, the adjustable chest strap sits too low for a 5’4″ frame, as well as for bustier testers, but fits a 6’2″ (flat-chested) tester just fine.

One of our favorite elements was how easy this cooler was to clean. After dealing with sticky, messy run nutrition, we were relieved that a quick wipe-down with a wet cloth was all it took to clean. For tougher stains, we tackled them at home with dish soap and water post-race. As a perk, the Deep comes with two Titan Ice Wall ice packs, which slide into zippered pockets on either side of the primary cooler compartment.

So, whatever it lacks in carrying comfort and adjustability, it makes up for in ice retention results and storage options. If you’re headed out on a solo mission or need extra storage, this might just be the cooler for you. Considering the scale, this pack could hold 24 12-ounce cans with room for ice.

The brand also launched a second eco-friendlier model with an exterior that’s made from recycled plastic bottles: The Titan Eco ($50), which is smaller (capacity for 24 cans versus 30) and costs less. One caveat: The smaller Eco option is only available at Target.

Swooping the crown, the ICEMULE BOSS ($380) is a serious backpack cooler built for rugged adventures. It’s also the undisputed champion when it comes to ice retention. Topping our tests, the BOSS kept ice frozen for an impressive 133 hours (5.5 days), outlasting every other backpack cooler we held to the yardstick. Made with polar layer XT insulation, this is your pack if maximum cooling power is the priority. As one of the biggest pack coolers, the design distributes and carries weight surprisingly well.

We tested the BOSS on hikes around the Grand Canyon, where it handled the hot, dry conditions with ease. Despite having one of the largest volumes in our lineup, it was also one of the most comfortable to carry. The pack features double-padded mesh shoulder straps, hip pads, an adjustable hip belt, and a sternum strap, which all add up for excellent support under heavy loads.

We were initially unsure about the wide shoulder straps, but they proved to be snug and supportive without limiting motion. That said, the straps are less ergonomic than, say, the REI Co-op Cool Trail Pack Cooler. However, the airflow across the upper back panel was better than most other packs, which made a noticeable difference while trekking in warm weather.

Built for rough handling and demanding terrain, this burly ICEMULE utilizes MuleSkin 1,000-denier fabric that can take a beating. Whether it’s tossed in the back of a truck, dragged through the brush, or brought on a river trip. It can handle being tightly strapped down to a whitewater raft or canoe. Multiple external attachment points make it easy to secure extra gear or tie the pack down.

We also celebrate the three spacious exterior pockets with waterproof zippers, which are a great bonus for organizing smaller essentials. The stout zippers feature sturdy pull tabs — and they do come with a toll fee of being a bit tough to open and close.

Ultimately, when we loaded the pack with a 10-pound bag of ice for testing on a half-day hike in Colorado, it was easy to forget the pack was on at all. It’s also a great choice for hikers who want to cover some distance. While the cooler excels at ice retention and durability, it does have some trade-offs. Food storage space is limited. Although it can fit 24 12-ounce cans with ice, the capacity feels a bit tight, given the pack’s overall size.

Looking for more internal storage space? Check out the Engel Roll-Top High Performance Backpack Cooler. Otherwise, the BOSS backpack cooler is our recommendation for adventurers who need to max out ice retention, durability, and all-day comfort. It’s an ideal cooler box for the times when we needed reliable cold storage on longer outings and didn’t mind trading a bit of internal space to keep our eatables chilled. 

The unique REI Co-op Cool Trail Pack Cooler ($100) is an adaptable backpack cooler with a removable cooler insert, so you can drop the liner for a traditional day pack. Essentially, you’re getting two pack styles in one piece of gear for only $100, which is a good deal if you’re not looking for a specialized item. 

For this price, you’re giving up the rigidity and support of a build like the RTIC 30 Can Backpack Cooler or stout ICEMULE BOSS. But this is one of the most modifiable hybrid cooler packs on our list. 

We most appreciated the padded back panel and padded, contoured hip belt, which elevated the load off our back. After loading the pack with canned beverages for boating on a Wisconsin lake, we could still carry the bag with ease. One caveat: The material doesn’t wick sweat super well, but it is slightly suspended for some airflow. The handle isn’t fancy but has a wide opening and is easy to grab — holding it, we carried the pack a full mile.

These trusty pockets are well-built and utilitarian. For our 32-ounce Nalgene water bottles and sunscreen, we used the two mesh water bottle holders, which are sandwiched on the face of side zippered pockets. With Bluesign-approved materials, the design is more eco-friendly than the other packs we tested. The exterior is made with recycled ripstop nylon, and the liner is recycled polyester.

According to our test, the Cool Trail is able to retain ice for nearly 77 hours, well above the claimed rate. To put the size in perspective, this pack could fit 20 12-ounce cans.

Loaded with utility, the feature-garnished UA Sideline 25-Can Cooler ($134) genuinely stands out from other backpack coolers we’ve tested. Between soccer tournaments, park meetups, and road trips, this cooler has become one of our go-to teammates. The design’s smartest features include a pair of integrated hooks on the backside that let you hang the cooler, which we typically used on a chain-link fence. It seems simple, but it’s been a game-changer — no more setting it in dirt or mud or worrying it will get knocked over.

The Sideline consistently keeps drinks cold throughout long, multi-game days. Even with drink refills between sessions and regular shutting and jarring, the ice held up well enough to keep everything chilled from start to finish.

Similar to the Cotopaxi Hielo 24L, the roomy clamshell lid made it easy to quickly pack and grab drinks, even when thirsty kids were hovering. A pocket on the lid’s underside was perfect for stashing granola bars or snacks we didn’t want squished or soggy.

Sideline comes with a detachable mesh bag that hangs on one side, which we typically use as a waste bin. Whether it’s empty wrappers, banana peels, or random snack debris, having a designated spot for rubbish has been super helpful when there’s no trash can nearby. 

To dial in the sizing, this cooler pack includes the UA-leveled strap system. It’s a simple addition: The undermost portion of the shoulder straps are labeled with numbered lines, so you can make sure they’re even and that the weight is well distributed. We didn’t find it totally necessary, but the kids enjoyed it.

They loved making sure the numbers matched before slinging it on, which gamified carrying the cooler. And admittedly, when toting it from the parking lot to many different soccer fields, the balanced weight alongside the padded back panel and cushioned straps was really comfortable, even when fully packed.

We liked that the front offers plenty of attachment points, perfect for clipping accessories like hand sanitizer, water bottles, or even hanging cleats. The internal hardliner adds structure and makes the pack crushproof — it easily withstands being tossed in the trunk with heavy gear bags. Season after season, the UA Sideline has earned its spot in our rotation for sporting events and beyond. Functional, durable, and designed with real-world use in mind, it’s become our MVP from the dugout to the sideline. 

As a day-use cooler, the Cotopaxi Hielo 24L Cooler Backpack ($200) is a vibrant, one-of-a-kind design that offers solid performance. True to Cotopaxi’s style, each pack is made from repurposed materials, meaning no two are exactly alike, giving it plenty of personality along with its practical features.

We used the Hielo on day hikes around Moab, where it served us well in hot, dry conditions. It kept drinks and snacks cold for more than 8 hours, even with frequent access, making it a reliable choice for active use and snack breaks on the trail. While it doesn’t offer multiday ice retention like some heavy-duty models (such as the Engel Roll-Top High Performance Backpack Cooler), it’s more than capable for full-day outings. The main compartment is well insulated and roomy enough to hold lunch for a trio, along with snacks and drinks.

The clamshell lid and its generous opening made packing or unpacking especially easy. The sweeping lid is one of our favorite details for convenience and improving our bird’s-eye view into the cooler. Overall, the level of comfort is decent. While the padded back panel offers good support, the shoulder straps lack cushion and can become a grind on longer, hot hikes. An adjustable chest strap helps keep the pack secure.

Another appreciated element is the set of sturdy grab handles — located on the front, back, and sides — which made it easy to lift and maneuver the pack when fully loaded, especially in and out of a vehicle. The brain’s zippered pocket is a thoughtful detail, offering just enough space for small essentials like plates, utensils, a phone, or a wallet.

However, one thing to keep in mind: The cooler is not leakproof. As the ice melted toward the end of the day, water began to seep out when the pack was accidentally laid on its side. If you need to store it sideways, your best bet is to use ice packs instead of cubes.

We found the Hielo 24L Cooler Backpack to be a fun, functional choice for day hikes, picnics, and road trips. While it’s not built for long-term cold storage, its colorful design, ample room, and reliable day-long cooling make it one of our top picks for day adventures — especially if you want your gear to stand out and pop against the landscape.

For a full day outside, the Igloo Trailmate ($129) is a practical design that provides ample space for larger to-go containers. We loved how easy it was to pack larger provisions inside, thanks to the wide lid and roomy main compartment. The base gave the cooler structure, even when it was empty. And the crush-proof lid features a pull tab, which makes it easy to pull open once unzipped. 

Boasting very impressive ice retention, the Trailmate’s MaxCold Ultra insulation utilizes 20mm of high-density foam to help keep contents colder for longer — our ice retention test racked up a whopping 3.5 days. Then, during field tests in Utah’s high desert terrain, the Trailmate kept drinks and snacks cold throughout a full day, even after temperatures hit 90 degrees Fahrenheit.

In step with the Cotopaxi Hielo 24L, one of our favorite features of the Trailmate was the plethora of carry options, including grab handles on both sides. On top, dual webbing straps secure together via a padded, snap-button closure. The variety of handles made lifting it into the car or carrying it with a partner much easier. The side handles can also double as tie-down points, which came in handy for securing the pack on a truck bed.

Speaking of which, the durable welded exterior — made from coated 600D polyester — stood up well to the dirt, sand, and water during our desert outings. The insulated liner is fully wipeable for easy cleanup. A built-in bottle opener attached to the shoulder strap is a nice touch. There’s also a zippered pocket on the face for accessories like utensils, keys, or a phone. 

In terms of comfort, the Trailmate is nicely loaded. The design offers adjustable, lightly padded shoulder straps. A mesh-lined back panel adds breathability. And the chest strap helps to evenly distribute weight. While the Trailmate was comfortable to wear on shorter hikes, we found that the narrower straps began to dig in after about an hour en route.

The water-resistant zippers (on the main compartment and the front pocket) glide smoothly and include oversized pull tabs for easy handling, even with wet or sandy hands. The zippers are water-resistant, not waterproof, and we noticed ice melt seeping through the teeth by the end of the day when the cooler tipped over. If you’re using loose ice, know that the zippers aren’t waterproof. That said, the zippers effectively kept out dust and dirt while the cooler rode in the back of an open truck. 

While it’s not built with waterproof zips, it performs impressively on warm-weather trips. Beyond cooling prowess, the Trailmate backpack cooler balances storage and ease of use. It delivers practicality and value for adventurers who need a spacious, easy-to-carry cooler for day adventures.

We’ve consistently put YETI’s coolers to the grindstone and have never been disappointed. YETI now has an extended family of the Hopper lineup, and we got our paws on the entry-level YETI Hopper M12 Backpack Cooler ($275). While the tidy size is manageable to swing over your shoulder and carry, the design doesn’t skimp on the freeze-power — our fare stayed fresh.

The Hopper M12 has an upgraded and safer iteration of the brand’s previous ultra-strong magnetic closure — and that sucker is powerful. The strip of magnets even fully blocks water from leaking out or in. Despite the strength, this closure is easy to open and, yet, it does stay ajar until you physically push the folds back shut.

We found the narrow opening and shape are best for drinks and the elongated height does indeed fit a bottle of wine. Stacking groceries doesn’t go far with this silhouette but a handful of snacks can certainly go atop the ice and cans.

Also, the two buckles that close across the top of the pack are not super long, and the material is rather rigid. Our tester found it was easier to take a knee to the upper material to get those two clipped. One of our favorite details about YETI is the tenacity and smoothness of the exterior material including with the Hopper M12.

This stuff is so easy to wipe down after getting smudges, too. And we really love the grab handle, which is super comfortable and wide to grip. Those shoulder straps are supportive and clean-cut, too.

Otherwise, the pack includes a pocket in front that reaches about half the bag’s height. There’s no zipper or Velcro on the pocket, but the envelope is stiff and tacos around whatever you slide in whether that’s your phone, wallet, or keys.

Four columns of attachment points run vertically on the pack, where you can clip gear via carabiners. YETI also designed in-house products that link up with the loops like a bottle holder and 3L gear case. With premium ice retention and a more accessible size and capacity for folks, the Hopper M12 Backpack Cooler is one of our favorite packs that we’ve tested. Also, this volume can fit 20 standard cans of beverages.

Looking for a no-frills backpack cooler? The ICEMULE Recycled Jaunt ($175) is the one we reached for time and again. We tested this cooler on packrafting and SUPing trips in the Elk and Sawatch mountains of Colorado. With a unique entrance, the roll-top waterproof closure lends itself well to watersports and peace of mind while it sits in the back seat.

We loved that the bright interior makes it easy to see what you’ve packed at the bottom. Lightly padded, we also really like that the shoulder straps of the Jaunt are great for short trips to the riverside or ocean sand.

Overall, this design is lightweight, simple, and sustainable. Made of recycled materials, it’s durable and easy to clean. The bottom is textured and rigid enough to stand up on the beach or uneven ground. The inside is shiny, like a whitewater raft, and rinses out clean. We appreciate the minimal seams in this cylindrical design and secure strap attachments.

We love the zipper pocket on the front for a phone, keys, or other small valuables, but you won’t find any other pockets or attachment straps. This cooler worked best when two people were headed out — with a secondary pack to carry other odds and ends — but was challenging for solo missions. If you’re looking for an all-purpose, simple, sustainable design that holds ice well, this cooler is a great option.

If you want a pack loaded with pockets, don’t miss the Titan by Arctic Zone 24 Can Backpack Cooler, which retains ice for a bit longer, and has eight unique pockets — it just weighs more than twice as much as the Jaunt.

The test scores were good, too: The Recycled Jaunt retained ice for 75 hours. To put the size in perspective, this pack could hold 22 12-ounce cans with room for ice.

Sometimes, we need a cooler and a daypack — but not the hassle of carrying two separate bags. REI Co-op Cool Trail Split Pack Cooler ($85) is a clever hybrid that combines both, offering the functionality of a cooler with the comfort and convenience of a backpack. This design differs from our long-time pal, the REI Co-op Cool Trail Pack Cooler, which is slightly larger, heavier, costlier, and garnished with a hip belt. While the Trail Split packs lower ice retention, it still served us well on day trips, especially when our overall haul is less.

We tested the cooler on day hikes around Mesa Verde National Park and while crewing a scorching 50K trail race out in the desert. The lower-tier insulated compartment easily held ice, drinks, and snacks — enough for a day out with a family of 3, or up to 12 cans if you just pack beverages.

The upper compartment offered plenty of space for gear, making it perfect for stashing extra layers, socks, nutrition, and hats. This dual-compartment design was our favorite at aid stations, letting us grab what we needed — cold drinks or dry layers — without fumbling through multiple bags.

The padded shoulder straps and back panel were comfortable, even when the cooler was fully loaded. The adjustable chest strap made it easy to dial in a good fit for different body types. Overall, the pack felt supportive and well-balanced. Only on longer hikes (over an hour) did we wish we were wearing the waist belt that the pack’s big brother offers.

Expandable side pockets securely fit large 32-ounce water bottles, which is a nice touch for staying hydrated on the move. However, there are a couple of considerations to keep in mind: The ice melted quickly in the 85-degree weather. And after 6.5 hours on the race course, the ice had melted enough that when the pack tipped over, the cooler compartment began to leak through the zipper.

The zipper isn’t leakproof, and the boxy base usually stays upright. However, the ice compartment will leak if it’s knocked over. If you need a backpack cooler with serious storage and superior ice retention, consider the ICEMULE BOSS, which has spacious pockets and premium ice retention among all the backpack coolers we tested.

Even so, the Cool Trail Split Pack Cooler delivered a solid balance of cold storage and dry space. We found it especially well-suited for crewing races, day hikes, picnics, or any outing where we needed to carry a handful of perishables plus gear. While it’s not leakproof and ice retention has limits, the pack’s versatility makes it one of our top picks for a split cooler design.

The Eddie Bauer Recycled Bygone Backpack Cooler ($70) is reminiscent of your childhood lunchbox. This stylish cooler looks excellent at a lakeside picnic. Our tester took this cooler down the Gunnison River on floating trips and for lakeside afternoons in Crested Butte, Colorado.

This cooler is lightweight and simple in design. We appreciated that the interior fabric wipes clean easily. And we love the mesh zippered pocket inside the lid for smaller food items. To carry the goods, the side pockets and spacious front sleeve pocket are great for your water bottle, sunscreen, and a book for a day at the lake. And the shoulder straps stow away in a back pocket with a solid top-handle carry option for simplified carrying.

We suggest ice packs (versus ice cubes or blocks) to keep your food and beverages cool, as the zipper is not waterproof, and the tall cooler tips over easily on uneven ground. If that’s key for you, check out the RTIC 30 Can Backpack Cooler, which has a super sturdy base and remains upright with zero collapsing when sitting on the ground. We also wish the Bygone cooler had a zippered outside pocket, like the ICEMULE Recycled Jaunt, for a phone and other valuables.

However, we wouldn’t take this cooler on longer hikes because it lacks padding and adjustability as a backpack, and its ice retention decreases quickly in direct sunlight. But, if you’re looking for a small, simple cooler for a day outside, this is the cooler for you. Checking with the ice lab, the Bygone retained ice for 48 hours. To put the size in perspective, this pack could hold 20 12-ounce cans with room for ice.

For shorter day trips, we gravitated toward the Titan by Arctic Zone Deep Freeze Welded Backpack Cooler ($165), which offers two cooler compartments that we liked for the separation of drinks and food. We tested this Arctic Zone pack on a full-day fishing trip on Colorado’s Taylor River on a warm summer day.

We appreciated the ability to use cubed ice for canned beverages in the bottom compartment and ice packs for food and more fragile items in the top compartment. Both compartments have waterproof closures for peace of mind when hiking with the backpack or throwing it in the back of the car. The rigidity and durability of this cooler were great for a full day of exploring river banks and picnicking in high country fields. 

These backpack straps sit high, which pulled the weight of a fully loaded cooler up and off the tops of our shoulders, and the back panel offered ample padding and airflow. However, we wouldn’t recommend this cooler for longer trips or extended hiking. The ice retention suffered in the heat and direct sunlight. The placement of zippers, handles, and shoulder straps made the cooler uncomfortable to carry for long stretches of time.

Checking out the test results, the Deep Freeze retained ice for 40 hours on the bottom and 48 hours on the top. To put the size in perspective, this pack could hold 20 12-ounce cans with room for ice.

With a smooth yet durable exterior, the Hydro Flask Day Escape Soft Cooler Pack ($200) rewarded us on a double-date hike in Colorado’s Elk Mountains. Our quad packed all the tasty fare from champagne and dark chocolate to strawberries, lunchmeat, and bread. We loved that the top zipper is waterproof and bombproof — it’s also silent. There’s hardly a stronger, more durable waterproof zipper than the one on this backpack cooler, so if that’s your closure preference versus a roll-top, the Escape should be at the top of your list.

This cooler’s malleable walls feel rather buttery and lean, so we were surprised by the overall comfortable, ergonomic support as we trekked. We were happy to wear this pack and these padded shoulder straps for longer hikes and extended periods.

Despite its light weight and flexibility, the pack is structurally sound with durable handles and 600-denier polyester waterproof material. The chest strap stabilizes the shoulder straps; Otherwise, they annoyingly slide around. We also dig the stretch mesh side pocket, which easily fits a 1L bottle or utensils.

The downside is a watertight zipper takes two hands and more time to open and close than a traditional zipper. With a similar hand feel, the ICEMULE Recycled Jaunt also has a light, durable exterior but instead of a waterproof zipper, the bag has a roll-top design. Both options keep water out and ice in, but it’s a personal preference if you want to muscle a strong zipper or take a few extra second to curl the closure.

To put the size in perspective, this pack could fit 36 12-ounce cans. It truly keeps the temps low. The Day Escape is able to hold ice for nearly 60 hours, based on our test, which is above what the brand advertises.
