Simply throw Swig’s new Packi Backpack Cooler over your shoulder and keep on going. 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 be fully opened, and remain open, so it’s easy to fill and easy to use. It features two easy access Swig-sized side pockets with magnetic snaps, as well as a secure waterproof back zipper pocket that is perfect for your phone, keys and other valuables. The padded adjustable straps are curved and lined for comfortable carrying and there are additional handles for quick grab and go lifting. The colorfully durable exterior fabric is wipeable and waterproof. And our extra-thick closed-cell foam lining provides double the insulation capability, without extra weight or bulk you don’t want to carry.
