12 CAN COOLER. The FlexiFreeze 12 Can Cooler is a patented design with 60 re-freezable ice cubes sewn right into the sides of the cooler to surround the contents in cold. Nothing outperforms the cooling power of natural ice. FlexiFreeze uses 100% pure water to provide long lasting cold without the soggy mess of ice alone. Zippers on the top and bottom of the cooler allow it to fold flat and store conveniently inside your freezer. Say good-bye to blue goo and chemical gel packs forever. Just fold flat and store the cooler in the freezer and it's ready to go whenever you are. Made with safe and durable materials, the cooler can be frozen over and over again. Freeze It, Zip It and GO!
