Available in several Backpack sizes, these coolers will hold ice for 3+ days! Weighing in at only 4lbs, the Snow Coolers combine the chilling ability of a roto molded cooler, with the mobility of a soft-sided cooler. The Snow’s interior liner is made from leak proof, sweat proof, PVC-free FDA Food Grade material and is Prop. 65 compliant. Snow Backpack Coolers perform exceptionally well in direct-sunlight applications.
