It's like a koozie. Only better. The Arctican bests the venerable summertime drink wrap in a number of areas. Using a cooling core that you store in the freezer, it can keep your drinks colder than a traditional foam cover, and can do so for up to three hours, or long enough to enjoy several favorites before it's time to re-freeze. It also looks way better, too, with a double-wall stainless steel build, and since it fits most 12 oz. cans, it can handle everything from craft beers to artisinal sodas. Or Mountain Dew. Your call.
