There’s not a hard bottle out there that’s cleaner, greener, and more flexible than a Platypus SoftBottle. Each one comes with our Clean-Taste Guarantee™ and it’s made with zero BPA. The SoftBottle is green, too, because it’s ultra-reusable and lightweight, it uses less energy and materials. Finally, your SoftBottle defines flexible. It fits in a drink holder, a round pocket, a flat pocket, or any hand. When empty, it rolls up and fits anywhere you want it to fit. Plus, it weighs 80% less than hard hydration bottles. Available with the Closure Cap.
