Hydrapak ultraflask speed 600ml

The ultraflask 600 ml is so light you might forget you're carrying it. Weighing just over 40 grams, it allows for optimal hydration no matter what kind of runner you are. Its flexible material fits in most pockets, shrinks as you drink to minimize water movement, and can be used with or without the tube. Equipped with a new feature, the SpeedFill cap, it makes refilling super-fast.
