The YETI Hopper M20 Backpack Cooler is the perfect refreshment hauler for any day trip or weekend get together. Constructed with high-density fabric, the interior and exterior are puncture and UV ray resistant. The magshield opening uses powerful magnets to create a leak-resistant shield that stays open when you need it and easily closed with a gentle push. Keep your personal belongings safe in the deep front pocket and hitch on your important gear to the front grid loops. The closed-cell foam insulation will keep all of your drinks and snacks ice cold for hours and the leakproof welded liner prevents any water from soaking your pack. Comfortably carry your backpack cooler with the reinforced double-stiched handles and ergonomic straps that evenly distributes the weight.
