This Cooler has plenty of room to store what you need to keep cold. The outside is made of heavy-duty polyester & the inside utilizes a high density insulation. Includes an adjustable shoulder strap for carrying comfort. This cooler bag has space to store water bottles, beer, soda extra snacks and small gear—a zippered mesh pocket on the top. The soft liner is safe for use with food and drinks. Antimicrobial, product-protecting properties are built into the flexible lining to resist odor, mold and mildew, making it easy to clean between uses.
