The AZ Pro 16-Can Zipperless Cooler features a “flip-open”, patented Zipperless™ lid that provides quick access to food and drinks. The interior has SuperFoam® high performance insulation to provide superior cooling that keeps ice up to 2 days! The interior also includes a durable HardBody® liner with SmartBin™ that allows you to keep hard stuff like drinks separate from soft stuff, so sandwiches and other soft foods don’t get crushed.
