There's nothing worse when camping than losing your beer in the wilderness. (Okay, there are lots of worse things, but none that you're all that likely to experience). This Glow In the Dark Koozie ($6) can help prevent such a problem. Made by the outdoor lighting experts at Coleman, it accommodates most 12 oz. cans, helps keep them cold, and ensures that you'll be able to find them in even the darkest situations.
