Products We Tested
How We Tested
Our reviewers spent 18 hours testing one of the most popular backpack coolers on the market. To get the most complete results, our testers loaded it up with their food and drinks of choice, left it in the hot sunlight for hours, and opened it back up to eat, drink, and assess its effectiveness. We asked our reviewers to consider this backpack cooler’s most important features — from its design to its performance — and we’ve outlined them here so that you too, know what to look for when shopping.
What to Look for in a Backpack Cooler
Extras The world of backpack coolers is a surprisingly sophisticated one — these days, there are plenty of advances in design and fabric technology that add to what seems like a fairly basic purchase. Look for the extras that are right for you, whether it’s multiple storage spaces for cutlery or anti-mildew fabric.
Value If you need this cooler for a single hunting trip each season, you can likely get away with a quality but cost-effective option. However, if you’re looking for a cooler you can take on those twice-monthly camping trips, you may want to splurge on one that’s especially comfortable, durable, and tailored to your needs.
Activity There are all-purpose coolers that definitely do the job, but you’ll also find ones built specifically for certain activities — like overnight hikes into the woods, picnics, and hunting. Think about how you’ll use this cooler and look for models that cater to your pursuits.

What We Don't Like
Difficult to clean
One of our reviewers, who took this cooler on a light hike to the beach, was immediately impressed with how effective it was at chilling her food and drinks over time. “I was at the beach for a full six hours with the cooler out in the sun the entire time,” she explained, “and all of my drinks were still very cold. My food was also colder than any other time I've gone to the beach with a different cooler bag.” Other highlights were this cooler’s comfortable straps and sturdy build. Unfortunately, though, our testers thought it was a little bulky overall and that its thick interior insulating material was difficult to clean.
