Take your snacks and sips on your next adventure if you pleasethis backpack cooler has your *ahem* back. It has a roomy interior that holds up to 30 cans when closed. (Theres an insulated, water-resistant lining, so you can pile in the ice.) And thanks to that roll-top design, all you have to do is unroll when its time to picnic. The padded, adjustable straps go easy on your shoulders, while the attached bottle opener lets you pack one less thing. Expandable side slots for water bottles and a front pocket for your valuables, too? Oh yeah. Includes Seattle Genetics branded canteen in "Unicorn Magic", 16 oz.
