Made out of neoprene. What is neoprene you may ask? Neoprene is what scuba divers wear. If you are searching for "the good ones," the ones that last longer, insulate better, and keep their shape, this is what you are looking for. Not everything you see on the internet that looks alike is the same. Don't be fooled by similar products described as "scuba foam" or "polyurethane foam material".
Fits most 12 oz cans and some bottles
Collapsible for easy transport and storage
The thick neoprene material keeps your drink cold and your hands dry.
