This insulated bag is divided into two sections: the top mesh section (with drawstring closure) is designed to hold clothing, towels, etc. The bottom section is an insulated cooler (featuring ThermoGuard) that keeps food hot or cold for hours. This cooler section has a heat-sealed waterproof lining to eliminate leaks. The Zuma Insulated Backpack also has one large zippered pocket which keeps your essentials/valuables at hand. Stylish, light-weight and functional, the Zuma from Picnic Time is terrific for day trips, hiking, the beach, sporting events, and fishing. Makes an excellent gift item.
