Small, but mighty. When you’re on the run, UltraFlask 300 ml is ideal for quick hydration straight from your hand, the belt or vest. It shrinks as you drink, minimizing water movement, and carries our Beyond Guarantee.
Part of the ultra-light series, the 450 ml is so light, you might forget you brought it. Weighing in at just over an ounce, it’s optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimize water movement and it can be used with or without the tube. Ultra light weight, ultra useful.
Go big. The largest of our ultra-light series, the UltraFlask 600 holds more so you can go the distance. Its soft material allows it to fit snugly in most vest pockets and it shrinks as you drink to minimize water movement.
