When compared to other soft coolers in our guide, a few design choices—like placement of the side handles under the hook point for the strap making it feel very cramped—knocked a few points off. We packed the coolers with the stated capacity of cans (when possible); we also filled the coolers with ice once the cans were packed. Once the coolers were full, we began testing for portability and durability by carrying the coolers around the lab and up and down steps and pushing them off tables onto a concrete floor.
To keep the weight down, this Pelican soft cooler’s insulation measures only half-an-inch thick. It kept its interior below 40°F for 27 hours—one of the lowest of any of the soft coolers we tested. A tough, reliable soft cooler can keep your food and beverages cold while you hike, take a day trip, picnic, or tailgate. Best of all, unlike a hard-sided cooler, many of the best soft coolers can be collapsed down for easy storage when not in use. Dry bags are a staple of river trips, as are heavy, bulky hard-sided coolers.
We’ve taken it to campsites, beaches, and potlucks with friends and family, and it’s been appropriate in all settings. The waterproof design keeps everything inside and outside from getting too wet. The cool riser technology keeps hot surfaces from ruining the cooling process. Pockets are included on the front and back for small drinks or snacks in between rounds or halves of the game. The Daytripper’s Commuter Bag and Dual Compartment Tote are the smaller options, weighing in at 1.62 lbs. And 1.79 lbs., respectively, while the Tote and Backpack weigh between 3 and 4 lbs.
Still, as you add insulation thickness and rigidity to improve performance, those benefits start to diminish. It’s hard to gauge how stiff or user-friendly a soft cooler might be from a product description since few manufacturers list the thickness of their cooler’s walls in their specifications. Many longer-lasting soft coolers weigh between 5 and 10 pounds, which gets heavier as you add heavy liquids and ice. Consider how long you need a cooler to retain cold and how far you might be carrying it on an average outing as you balance weight and performance concerns in your purchasing decision. Because of their size, lightweight construction, and other features—like being equipped with padded handles, bottle openers, or backpack straps—soft coolers offer more flexibility than traditional hard-sided coolers.
For the ultimate in portability, soft-sided backpack-style coolers are the way to go. The designs borrow heavily from hiking daypacks, sharing features like shoulder straps, padded backpanels, and exterior pockets for added gear storage. Additionally, backpack coolers are fairly expensive considering their modest storage capacity and all-around performance (the Day Escape is pretty average in this category at $200). But if the approach to your favorite picnic spot or fishing hole involves walking more than a half mile or so, it may be worth the investment.

We also started tracking the internal temperature of the coolers with the ThermoWorks Signals thermometer to see exactly when temperatures began to rise. Most cooler manufacturers provide a “claimed ice retention” spec in their product listings (YETI is one major brand who does not). From our list above, times range from just 4 hours at the low end for the Hydro Flask 20 L Insulated Tote to three or four days igloo soft cooler at the high end for Engel’s HD30 (24 hours is pretty standard). That said, we always take manufacturer-provided specs with a grain of salt, and there isn’t an established, standardized test here. In practice, most of the claimed ice retention times feel quite inflated to us, perhaps due to extremely favorable testing conditions (storing the cooler inside with the lid closed in cool temperatures, for example).
