Shrinks As You Drink.

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.

  • Keep hydrated as you run with this collapsible flask
  • Flexible TPU construction shrinks as you drink
  • Screw cap with removable drink tube and bite valve
  • Can be frozen or filled with hot water
  • Ideal for hydration vest, belt, or pack pockets
