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 down into a cute little ball when it's empty. The Speedfill cap flips open for quick filling of liquids or ice on race day. If you are a straw person, the UltraFlask speed is straw or standard nozzle compatible, so take your pick! If you want a flask that does it all, consider getting a HydraPak UltraFlask Speed - or a few.

  • Speedfill cap and large opening nozzle make refills a cinch.
  • High flow bite valve automatically seals for a leakproof run.
  • 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.
  • Drinking straw included so you can sip as you skip down the trail.
