    600 ml soft flask

    Great bottle with a variety of uses. Great for travel as it folds up. The straw makes it easy to drink from. Able use with a variety of packs.

    Used On Every Long Run

    I use this for every long run in my ultra marathon training and for long races. It fits perfectly in the front pocket of my Endurance Pack. I have a nutrition mix I fill it with.

    Always had the hard bottles before this one so I grabbed two soft flasks with the vest. Easy to clean, easy to refill and easy to handle on the run.
