The roomy Arctic Zone 30-Can Zipperless™ Cooler features our unique “flip-open”, patented Zipperless™ lid that allows quick access to food and drinks. Inside there is a durable HardBody® liner with SmartShelf™. The SmartShelf™ allows you to keep hard stuff like drinks separate from food so sandwiches don’t get “smushed”. If you want to use the entire liner, the SmartShelf™ easily removes to provide one large compartment. The interior also features high density thermal insulation to keep contents cold and an Ultra Safe® leak proof, easy clean lining. Designed for convenience and usability, this cooler has a zippered front pocket and an adjustable Backsaver® shoulder strap with shoulder pad that centers load weight to reduce muscle stress.
