Throw Swig’s new Packi Backpack Cooler over your shoulder and keep it moving! Just add ice to keep 4 gallons (16 liters) of your favorite drinks and snacks cold for hours. The unique, wireframe, zip-top construction allows the cooler to remain fully opened while being filled and used. It features two, Swig-sized side pockets with magnetic snaps, as well as a secure, waterproof zipper pocket that is perfect for storing your phone, keys, and other valuables. The extra-thick, closed-cell foam lining provides two times the insulation capability, without extra weight or bulk you don’t want to carry. Best of all, the colorfully durable exterior fabric is wipeable and waterproof.
