Soft Flask – 500ml


Hydrapak’s UltraFlasks™ are designed to conform to the shape of your body, compressing as you drink – this means reduced sloshing and bouncing, less spillage, and an easier time drinking Tailwind. The clear design eliminates guessing how much hydration you have left and when it’s empty, the pliable body of the flask collapses into the hard top, making this the perfect bottle for multi-stage events.

Our soft flask is compatible with your existing gear and has been successfully tested with Ultimate Direction, Salomon, and Nathan vests as well as countless bicycle jerseys and backpacks.

  • Dimensions – The hard plastic top measures 8.5 x 6.5cm wide and the body measures 7cm tall
  • Capacity – Holds up to 500ml/17oz
