The cooler backpack is an insulated backpack for all your favorite camping food. Fill it with ice or use the Ice Pack to keep your food or beverage cold. The roll-top system makes it easy to close and open; a buckle (with a handy integrated bottle-opener) secures the content in the bag. Nylon outer fabric makes the backpack rugged and durable. The inside lining is made of waterproof PU-coated polyester, which can be turned inside out for easy cleaning. EVA foam insulates the bag while providing padding for your back, making it comfortable to wear. The backpack is equipped with adjustable 30mm shoulder straps for comfortable carrying. The exterior pocket will fit your kitchen accessories or hold your bottle caps. The 22 L pack easily carries food for you and your friends. It has space for 24 of longnecks or a couple of BIBs.
