Over the last 5 years, we've vetted, purchased, and tested over two dozen soft coolers. Our latest trials compare the best 13 models of 2020. Soft coolers offer portability and versatility that traditional hard coolers can't. From lunchboxes to beach days, we meticulously tested these soft-shelled sidekicks side-by-side to discover which are the best insulators, the supremely rugged, and the sensationally portable. We fully loaded these coolers, walked with them for miles, and went through hundreds of pounds of ice. No matter your budget or needs, our exhaustive testing will help you identify the perfect cooler for you.Related: Best Cooler of 2020
Best Soft Cooler of 2020
Best Overall Soft Cooler
We are impressed by the Engel HD30. It provides top-notch insulation, keeping raw foods safely cold for just under three days. Many soft coolers have difficult zippers or narrow openings, but the Engel stands out as remarkably easy to use. With sides that unclip, the top can conveniently be opened further to allow quick loading and locating of contents. On top of that, this is one of the largest coolers we tested, fitting an impressive 48 cans, making it a solid contender to guard your food and drink for a long weekend of camping. Despite its bulky size, the Engel is more portable than we expected, featuring a practically painless two-person carry if you've loaded it up with heavy items. Its high quality, durable construction lends credibility to this model's ability to survive plenty of use and abuse for many years.
Of course, large capacity always comes with a trade-off in how far you're willing to carry it. Even with a friend to help, this isn't the ideal cooler to cart a mile down the beach. But with all sorts of additional helpful features like extra handles, a removable bottle opener, and an additional pocket, the Engel outcompetes all the rest for yet another year, remaining our favorite model. It may not be cheap, but it is impressive.

Best Bang for Your Buck
AO Coolers 24 Pack Canvas Cooler
At first glance, this cooler may not look like much. It doesn't have the laminated exterior and waterproof zipper that so many others boast. Yet underneath this unassuming exterior, the AO Coolers 24 Pack is a solid cooler that's simple to use and easy to love. Thick insulation provides reliable insulation for an above-average amount of time. A single opening that's longer than the interior of the bag makes it uncomplicated to load and later locate what you're seeking. One large zippered pocket on the outside provides a well-above-average amount of dry storage, and duffel style handles can be joined together for easy transportation. Its flexible shape not only allows you to fold it flat for storage (which most the competition can't claim) but also more easily accommodates tall objects, such as taller 750 ml bottles.
The AO does lose some points for lack of a waterproof zipper and exterior - though the regular zipper is much easier to use than waterproof ones that require a lot more tugging. And though its hull isn't as stiff and impenetrable as some of the others we tested, it's still pretty strong and well-constructed. The shoulder strap could be longer to accommodate cross-body wear better. However, these drawbacks are minor. All in all, this cooler performs well above its price tag, providing the most value among all models we tested.

Best for a Tight Budget
Arctic Zone Titan Deep Freeze Zipperless
The Arctic Titan Zipperless offers great utility for a steal. Despite having some of the thinnest insulation of any model we tested, it still managed to maintain recommended food temperatures for close to two days, reaching just over the group average. The zipperless design for the main compartment makes it completely painless to use, and the hard plastic interior makes it simple to pack. A removable shelf adds functionality, keeping sensitive items out of melted ice, and numerous pockets adorn the outside for wine corkscrews, napkins, and silverware. It even comes with a bottle opener clipped to one end.
The low price tag does come at the cost of some durability, though. This is not the model we would expect to last the longest, as its materials and craftmanship are not top-tier. Many of the features added on seemingly everywhere also ride the line between being handy and superfluous. The shelf is easy to knock loose and fall into the main chamber, and the bottle opener is far from the best. This isn't the model we recommend for hardcore use, but if you need a small cooler for occasional use and want to spend the least, this model offers decent value.

Best for a Personal Cooler
YETI Hopper Flip 12
Year after year, the Yeti Hopper Flip 12 continues to impress us. This tried and true design boasts impressive insulation for a small cooler. Its shape and size are convenient and easy to use with a simple design that simply works. Like Yeti products have come to be known for, this cooler is strong and primed to tackle all your wild adventures. The latest rendition of this crowd favorite includes a top handle (in addition to the two side handles from previous iterations) to make grabbing and going even more effortless.
While the Flip can have other Yeti accessories (like bottle openers and extra pockets) attached, it doesn't actually come with any additional pockets or features, while many other coolers do. Those extras, well, cost extra - on top of an already expensive cooler. Though this newest version costs marginally less than its predecessor, it's still among the more expensive coolers out there. But if you want a personal cooler that just won't quit, the Flip should be on your shortlist.

With many exciting backpack coolers now on the scene, we retested this pack next to several new models, and the IceMule Pro just can't be beaten among the backpack-style coolers. Though this cooler requires a bit of a learning curve, it proves itself incredibly easy to use and comfortable to carry. The large roll-top design allows easy access to its contents without having to remove everything on top to reach that last cold soda at the bottom. Soft, wide shoulder straps and a longer torso length make this pack much easier to carry than its more rigid competitors. With a lightly padded back panel, breathable mesh, and a more flexible structure, we found ourselves much less sweaty hiking this model down the trail than any other backpack cooler. It also performed quite well among backpack models in our insulation testing and is solidly durable.
It took some time for us to figure out the best way to use the inflatable sides to maximize both capacity and insulation, but once we got that down, we enjoy the extra padding the air-filled walls provide. However, we can't quite get the top rolled tight enough to be waterproof, though it only leaks little drips when completely inverted. While we wish it had more pockets on the outside for extra items, we enjoy using the IceMule Pro, and it is our go-to choice when heading out for longer distances.

Notable for Cold and Dry Storage
REI Co-op Cool Trail Split Pack
Ever wish your cooler could haul more than just the cold stuff? Want a jacket and a book to go with that picnic? So do we. We like the well-thought-out design of the REI Co-op Cool Trail Split Pack for making sure you never have to leave your sweatshirt or frisbee at home. The bottom half is a small cooler that fits provisions for you for the day while the top half holds all your dry goods. Several other useful pockets can hold easy-access items or wrappers and trash. This is also one of the most comfortable backpack models we tested, and we have no problems carrying it for miles to an exciting destination picnic. As a bonus, it's also among the least expensive coolers we tested.
However, the recycled ripstop nylon of this bag doesn't strike us as overly impressive. We worry a bit about its longevity, especially of the bottom of this bag, if it gets dragged over rough surfaces. And the attachment points of the sternum strap to the shoulder straps are a bit looser than we would like them to be. The relatively thin, small cooler section doesn't hold a ton of items but might suffice for day trips. And though the cooler material is waterproof, the zipper isn't - so don't store this bag on its side. Despite a few flaws, we still love this useful daypack cooler for adventures that involve more than just a cooler full of food.

She spent a summer living out of her teardrop trailer and isn't one to give up on the comforts of a fresh meal while she's out. Her background in scientific research helps bring structure and scrutiny to our intensive cooler testing process. Maggie is the GearLab cooler guru and has been testing coolers and other gear for GearLab since 2017, personally having tested over 50 different coolers, from traditional ice boxes to the latest in portable powered technology.
Before we started timing how long our drinks stayed cold, this review began with market research into which soft coolers are worth trying out. Every year the number of impressive-looking soft coolers seems to grow, and we've been expanding our selection of test-worthy models for five years. Our in-depth insulation testing was developed in conjunction with Steven Tata, whose background in engineering helped us to design realistic and intensive testing of these coolers. Testing consists of a quantitative ice melt test and extensive field use. The ice melt test was carried out in a controlled environment with the internal temperature of the coolers monitored and analyzed in accordance with the USDA's Refrigeration and Food Safety Guidelines. Field use takes place in a variety of environments, from hot desert hikes to road trips from Minnesota to California, for a well-rounded set of conditions. All this adds up to a comprehensive review, which will thoroughly equip you to make a great soft cooler purchase.

Analysis and Test Results
We pitted each model head-to-head to present you with the most comprehensive and transparent possible picture of each one's strengths and weaknesses. We scored each model's performance in each of the four key metrics that are mutually exclusive and critical to choosing the best one for your needs. Obviously, insulation value is one of the essential categories to anyone in the market for a cooler; otherwise, you'd throw your sodas and salsa or champagne and cheese into any old bag and call it good. But with so many coolers (and exceptional ones) on the market today, insulation value isn't the only important factor in the decision-making process. While we rank insulation value as 30% of each contender's overall score, ease of use and durability both account for 25%, and portability comprises 20% of the final score. By weighting each metric according to its importance to identifying the perfect cooler, we're able to provide an easily comparable overall score from 1-100 for each contestant.

When it comes to performance in soft coolers, you often get what you pay for in terms of durability and insulation value. Some of the most expensive products we tested offer some of the most impressive insulation powers and are made of impressively durable materials. However, the correlation of price to performance isn't a perfect linear relationship, and several models we tested buck the trend, offering exceptional value.
The AO 24 Pack is a good example of a functional and well-priced cooler. This inexpensive model offers excellent insulation in an easy-to-use package with adequate capacity and moldability. It's not as hip or chic as some modern options, but we found ourselves reaching for its functionality time and time again. The Arctic Titan Zipperless costs even less, and though it has some flaws, it still works and has a comparatively very low price tag. Even the Engel HD30 is a high-value item. Outperforming all the rest, this large cooler isn't the most expensive model we tested and is worth the investment for its supreme insulation prowess and excellent durability.
The FDA recommends keeping perishable foods that require refrigeration at or below 40º Fahrenheit; this helps prolong their freshness by slowing down the bacteria and other such nasties from growing inside. Keeping a larger cooler cold will require putting more ice or ice packs inside versus keeping a smaller cooler cold, as most coolers recommend at least a 1:1 ice to food ratio, if not even more ice. Making sure your items are cold before they go into the cooler is another way to add insulation value to any cooler. Keeping your food or beverages cold is the number one reason to purchase a cooler; thus, it is the most rigorous metric in our testing. Our head-to-head ice tests highlight which coolers provide the greatest insulation value.
We noted two critical temperature thresholds during our testing: 40º F and 50º F. While 40º F is the food-safe threshold recommended by the FDA, 50º F represents the average maximum ideal temperature for serving beer. Of course, the ideal beer-drinking temperature depends on the type of beer you're enjoying and your personal preference. The American Homebrewers Association breaks down the optimal serving temperature for many different types of beer. We chose 50º F in part as an average maximum ideal temperature for serving beer and also as a second benchmark temperature to easily grasp the rate of temperature gain in each cooler of melting ice.
The Engel HD30 outshone the rest in our intensive hot-room testing, lasting a full 68 hours, or just shy of three days, holding internal temperatures below 40º Fahrenheit, even when the external temperatures soared well over 100º F. The Yeti Hopper M30 lasted almost as long, though coming up short by six hours, managing a still-impressive 62 hours of USDA safe-food temperatures. However, the 50º Fahrenheit threshold difference between these two is much smaller. The Engel lasted 73 hours, while the Yeti M30 closed the gap, managing 72 hours, or exactly three days of refreshing beer temperatures. Both of these coolers are on the large side for this category and have very thick insulation and watertight fabric and closure systems. The Engel's watertight zipper effectively seals insulated sides that are nearly 2 inches thick. The Yeti M30 has gone away from having a zipper. In place of the zipper, the M30 has a leakproof magnetic strip that closes itself with a snap whenever your hand isn't in it. This helps to keep things colder even when you're hanging out with that one friend who likes to leave things hanging open.
As this type of cooler has become increasingly popular, the field has become increasingly innovative. Whereas once the presence of an airtight zipper and waterproof exterior was an indicator of insulation, now a wide variety of solutions have continued to impress us with their ability to keep things cold. Models with the now old-school approach of having a water/airproof zipper include the Engel, Homitt, RTIC SoftPak, Hydro Flask UnBound, and Yeti Hopper Flip and BackFlip. Other coolers have more traditional zippers that aren't watertight, yet they manage to provide effective insulation, including the REI Cool Haul and AO 24 Pack. They proved themselves worthy during our insulation testing, achieving 55 and 46 hours, respectively, maintaining sub-40º F temps despite lacking watertight zippers or waterproof exteriors.
In an interesting twist, the Arctic Titan Zipperless has neither a zipper nor a roll-top. It closes like an old school hard cooler, with a plastic lid that fits into a plastic body, lined on the outside by an insulated fabric bag. Even with this less-secure-sounding closure system, it still held ice for 43 hours during our testing, just above average. Another innovative solution is exhibited by the IceMule Pro, which has a roll-top closure system, just like a dry bag. Though it held an internal temperature of under 40º F for just 28 hours during our testing, it then proceeded to keep its contents below 50º for almost twice as long, providing 51 hours of chilled beer temps. Interestingly, another backpack cooler, the Yeti BackFlip scored similarly, keeping sub-40º contents for just 27 hours but also managing 51 hours of cool brews. Considering these backpack style bags are geared toward a single day's adventure, these test results are more than adequate.
It's also worth mentioning that of the coolers we tested, half of the 6 that managed above-average insulation testing results (keeping temperatures below 40º F for 40+ hours) are not watertight and are significantly more budget-friendly than the top two performers. The REI Cool Haul (55 hours below 40º F), AO 24 Pack (46 hours), and Arctic Titan Zipperless (43 hours) are all impressive insulators for single-day uses and cost a lot less than you might expect. The Homitt is watertight, proved itself worthy with a test result of 50 hours below 40º F, and is also easier on your wallet—though it later also exhibited some durability concerns that we'll address later. If your needs are modest, and so is your budget, all of these coolers offer good insulation at a fraction of the cost.
Ease of Use
Ease of is important. Some designs make using a cooler more enjoyable. We also found some options that proved frustrating to use.
To evaluate this metric, we focused on how easy the coolers are to load and unload: how they open, how challenging the zipper or closing mechanism is to use, and if they stay open while you packed them full, or if they require a second pair of hands. We considered how adaptable each cooler is to different sizes and shapes of contents: can it fit a carton of eggs for a breakfast cookout or a bottle of chilled Pinot Grigio for that fancy picnic? We also looked at the features each came with and evaluated their actual usability. As we discovered, just because a bottle opener is clipped onto the end, unfortunately, doesn't mean it will reliably open bottles.
One of the most frustrating qualities of many of the models we tested is their challenging zippers. So far, manufacturers haven't been able to produce a zipper that's waterproof and truly easy to use. Many soft cooler zippers not only require two hands to open and close but also quite a bit of straining and muttering through clenched teeth. The watertight zipper that performed the best is that of the Engel HD30. Though robust and watertight, its zipper is much easier to use and comes with zipper lubricant included, helping it to remain explicative-free. All zippered Yeti models (the Flip and BackFlip) and the RTIC SoftPak now come standard with zipper lubricant that helps to make their zippers glide more easily, though they aren't as smooth as the Engel. This lubricant also needs to be reapplied frequently. Each of these coolers features extra handles for more carrying options, tie-downs to attach them to your ATV or truck bed, and even some additional options like daisy-chain webbing to clip on your bottle opener or car keys.
Some other models are easy to use because of the excellent design or features they have. The IceMule Pro is one of our favorites once you get used to it because of its simple roll-top design and comfortable straps that make carrying this bag a breeze. The REI Cool Trail Split Pack is one of our favorites for daily adventures and solo missions. It brings together unique features that let you bring along both cooler goods and dry adventure accessories all in one handy backpack.
The REI Cool Haul and AO 24 Pack both have traditional zippers that are easy to use and just the right amount of additional design elements or features that make them quite handy. The AO is as easy to use as a simple duffel bag, and clips on the ends of the top zipper make it easy for the top to stay open while you load and unload it. One long external pocket has tons of space to bring dry items along with. The REI Haul features several webbing loops, two exterior pockets, and an internal zippered pocket to keep you organized. It has a bottle opener (that actually works) attached to it, so you'll never have to worry about forgetting one again. The interior insulation also slides out of the cooler's main body, making it even easier to load on the counter or clean in the sink after a spill.
If you wanted to stay home, you'd use your fridge. For an adventure, you need a cooler. But where do you want to go with your cooler, and how do you want to get there? Depending on the size and type you're planning to take with you, you may have already put some limitations on your adventures. Any cooler can be loaded up and thrown in the car, so we didn't think about that so much when rating portability. Are you heading from the parking lot to the beach nearby? Are you carting around lunch all day at the zoo? Are you hiking five miles to your secret fishing hole? The most portable cooler will be more comfortable to carry for longer distances and amounts of time.
We leave out the overall size of each contender from this section, as anyone could tell you that a smaller or less-packed cooler will be more comfortable to move around than a more massive, heavier cooler. The clear winners in this category are the backpack-style coolers, as this distribution of weight across both shoulders and resting behind you will almost always beat out a unilateral carry. However, not all backpack coolers are created equal. We tested five of this style, and the IceMule Pro is hands down our favorite for sheer carrying comfort. It has soft, wide shoulder straps, a longer torso for more even weight distribution, and a flexible shape to accommodate whatever you've filled it with. The walls of the cooler can also be filled with or emptied of air, which adds both insulation and comfort against your back. In the face of some innovative competition, for years now, the IceMule remains the most comfortable model we tested to carry on a multi-mile hike.
The REI Split Pack is also a soft, comfortable option that we don't mind carrying for miles on end. It doesn't fit quite as well as the IceMule, with a slightly shorter torso and less flexible shape, but is still much better than the boxlike rigidity of others we tested. It also has the added convenience of carrying more than just cooler items, helping to keep your hands free while you hike. The Yeti BackFlip is the only backpack model we tested with a waistbelt, but we don't think that wide strip of webbing adds much to this exceptionally rigid and awkward box. The Hydro Flask Unbound is also a bit of a disappointment in the backpacking cooler family. Though its straps are cushioned and comfortable, its overall shape is quite rigid and boxy, making it less pleasant than more flexible models — especially when weighed down with heavy beverages and melting ice.
Among the many tote and messenger style options we tested, we have our favorites. Models with helpful shapes, adjustable straps, and extra padding go a long way toward making these something you don't mind carrying. Some of the other reasonably portable bags like the Yeti Flip 12 scored well thanks to their well-padded shoulder straps and additional options to hand carry or partner carry them if they're loaded down. The REI Cool Haul is also a favorite, with its soft, malleable body and long padded shoulder strap that makes it much more pleasant weighed down across your body. The softer canvas of the AO 24 Pack is also far more comfortable bouncing against our sides as we walk than other models with more rigid forms.
If you're going to spend your hard-earned money on a piece of gear, you want it to last. This fact is just as true for coolers as anything else you own. The durability of any gear comes down to a few simple factors: the quality of its materials and components, the method of construction, and the overall design. The coolers we tested feature a wide variety and quality of materials. We assessed durability over months of use, paying attention to how they handle daily rigors. We threw them around, dropped them on the ground, and filled them to the brim with heavy drinks. We also packed, emptied, repacked, and bounced them around in back seats and truck beds, left them out in the sun for hours, strapped them into water-logged boats, and anything else we could think of.
The models that scored lower in our durability tests use light to mid-weight nylon or canvas with middle-of-the-road zippers and regular seam construction. The higher-end models feature heavy rubber or treated nylon, have heavy-duty zippers and components, reinforced and welded seams, and more robust designs and construction. All of these aspects affect the overall durability and lasting power.
The most durable coolers we tested are the Engel HD30, Yeti M30, and Yeti Flip 12. All of these coolers feature incredibly tough, wear-resistant outer fabric, durable components, sturdy zippers, reinforced stitching, and a design made to be used and abused. The Yeti BackFlip is similarly constructed from ultra-thick, durable material with a reinforced bottom and sturdy zipper, but has extra strap attachment points for the backpack harness prone to additional wear and tear from supporting the cooler over time. The RTIC, while not quite as impressive as the Engel or Yeti models, is also built of similar materials. It is made of durable, sturdy fabric but has a couple of longevity concerns that we don't find in the Yeti or Engel models.
The IceMule Pro is relatively durable and resistant to our abuse, though the attachment points of the straps seemed perhaps not quite as reliable or as robust as we'd like them to be. Not surprisingly, some of the coolers that performed the lowest in this category also have the weakest material. However, these coolers (the Coleman 16-Can and Arctic Zone Titan Deep Freeze) are also some of the least expensive we tested, so you might not be so upset about replacing them when they bite the dust.
While reviewing these products, we went out of our way to imagine what the every day, the unique, and the serious gear user and abuser might use them for, and we did those things: summer trips into the desert, long hikes on hot days, dinner parties in the park, sunny beach days, rainy camping weekends, and impromptu BBQs. We hauled these coolers all around and put them through their paces. In doing so, we have compiled what we believe is the most comprehensive review of soft coolers available. We hope that the information presented here helps you find the right cooler to fit your lifestyle.
