The Titan by Arctic Zone Zipperless Cooler keeps ice up to 3 days! The exterior includes a patented, “flip-open” Zipperless lid for quick access to food and drinks as well as an insulated front pocket. The interior features Deep Freeze Performance Insulation with a radiant heat barrier and a removable HardBody liner with SmartShelf. The SmartShelf allows you to keep hard stuff like cans separate from soft stuff, so sandwiches and other soft foods don't get crushed. If you want to use the entire liner, the SmartShelf easily removes to provide one large compartment. The Ultra Safe interior lining of the cooler is leak proof and has Microban protection. Designed for convenience and usability, this cooler also features an adjustable Backsaver shoulder strap with anti-slip shoulder pad and rugged exterior material that is tough, water and stain repellent and easy to wipe clean.
