Have you ever used one of those old school, cheap, foam koozies to try to keep a drink cold? Yeah, they don't work that well and the designers of ColdCan know it.
ColdCan has set out to change all that. Its designers have revolutionized the canned drink beverage insulating market with the use of Cryogel, which is made of a version of the same thing in NASA spacesuits that insulates astronauts from the harsh temperatures in space. Not only that, but ColdCan has made its container into an interchangeable system that allows you to connect a 16 oz adapter for your tall cans. ColdCan has a lid that keeps an open drink from spilling when the lid is on top. The container is waterproof, and floats, when closed. Soon the brand will release a bottle adapter as well. To top it all off, they are made in the USA!
