The CoolZuca Cooler has been designed to complement the unique patented Zuca line. A zip-in liner can be removed for hand-washing, and keeps the CoolZuca from leaking (as long as it is upright. The Insulated removable floor panel allows the CoolZuca to fold up and provides a shelf when needed to keep food away from wet cans and ice. I believe that Zuca is a great brand name and having this is a nice addition to all the other great Zuca products or simply use it by itself for reliable storage.
