Description

Minimize water movement on your run.

Your marathon is just three weeks away and you're hitting the peak of your training. So before you hit the pavement for that long run, grab the HydraPak Ultraflask Collapsible Water Bottle. Unlike traditional water bottles that remain bulky even when the water's gone, the Ultraflask shrinks as you drink to minimize sloshing and bulk. It comes with both a bite-valve cap and straw to fit your hydration preferences.

  • Soft water bottle for hikes, runs, and bike rides
  • Material is soft and flexible to shrink as you drink
  • Conforms to your hand or any pocket easy carrying
  • High-flow bite valve seals after every sip to stop drips
  • Includes removable drink tube for added convenience

so Simple

    use it in my running belt and it fits well and is a breeze to use, especially appreciated while on a grueling trail run!

    Lightweight !

    • Familiarity: I've put it through the wringer

    Awesome lightweight bottle that collapses down to save space in your pack. I also really like the small size to stick in my coat while skiing to grab a swig of water on the lift. After its empty and collapsed you will hardly notice it is in your coat!

    Spare Flask

    • Familiarity: I've used it several times

    Got this for other consumption than water. Great light weight little flask easy storage while backpacking.,

    Say no more to heavy water bottles!

    • Familiarity: I've used it several times

    Bought a few of the 600ml because they are great for long runs. No more being weighed down by heavy unused water bottles. Once you finished one of these just roll it up and pack it up.!
