Autoseal Kangaroo Water Bottle. I have been looking for something like this for a long time! A perfect companion at the gym or on a run when you want to take some money and credit cards (I window shop while running). This super-cool water bottle ($13) offers with a built-in compartment - so you can carry keys, an ID, money, a train pass and more when you’re on the go! (via FitSugar)
