Hydrapak's 300ml Ultraflask is a small, lightweight and collapsible sports bottle with silicone bite valve. Ideal for running hydration belts or vest pockets.

Hydrapak says:

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.

Hydrapak's 300ml Ultraflask, is the ideal size and material for fitting into small pockets of running packs, belts and vests. Being soft it reduces in size as you drink, taking up less space in your pack and also prevents the liquid from sloshing around. It has a wide neck opening which allows you to insert powders and gels in as well as water.
