HydraPak UltraFlask Speed
Continuing to lead the pack in soft flask innovation, the wizards at HydraPak pulled out all the stops on the UtlraFlask Speed. Designed with a soft material that will fit most hydration vests, belts, or any old backpack, there is no excuse to leave this featherweight flask at home. The shrink-as-you-drink design will keep your fluid bounce to a minimum, collapsing into a cute little ball when it's empty. The Speedfill cap flips open to quickly fill with liquids or ice on race day. If you want a flask that does it all, consider getting a HydraPak UltraFlask Speed - or a pair.
- Speedfill cap and large opening nozzle make refills a cinch.
- High-flow bite valve automatically seals for a leakproof run.
- The shrink-as-you-drink design cuts down on sloshing and space.
- Customizable cap lets you tailor your drinking experience.
- Available in 500ml or 600ml options.
2025 Update: The Ultraflask Speed soft flasks no longer come with the "drinking straw."
