On your next water-related outdoor activity, make sure to grab the Floating Marsupial. This handy wallet and keychain by our friends at Chums really does float! We tested it with 4 keys attached to a keychain (so probably about the weight of 5 keys) along with 2 credit cards. The bright red wallet was easy to spot in the water and floated at the surface. Mind you, it’s not waterproof, so the contents do get a little wet, but not a problem if you’re just keeping keys, credit cards and some cash secure.
