UBB and Barebones join forces for a bag that meets all your cooler needs: up to 20 cans. With a shape reminiscent of an icebox, the cooler bag can keep contents cold for 48 hours—even longer than most insulated thermoses or growlers. The wide-mouth (which hangs over the sides of the backpack) allows the opening to expand when unzipped. As such, you could carry two—one for ice and one for cans—and then combine as needed. Moreover, the backpack design makes it even more practical than most coolers out there.
