The Gallon Koozie design is nothing short of amazing. The neoprene material helps keep your gallon of water cool throughout the day. A clear plastic pocket in the front holds your smartphone, and allows you to use your touch screen phone through the plastic with out having to remove it from the pocket. It also has a clip to hold your keys, and a stretchy mesh pocket to hold other miscellaneous items to keep your hands free and pockets organized. Fits most gallon sized jugs.
