Tailwind Nutrition Soft Flask

Hydrapack's UltraFlasks are designed to conform to the shape of your body, compressing while you drink. Which in turn reduces sloshing and bouncing so that you can do more of what you want, drink. The flexibility of the soft flask allows it to fit well into your existing gear.

• Collapsible to be stored in a pocket after use
