The lightweight and flexible 500 ml flask is your practical accessory to stay optimally hydrated while trail running or mountaineering.

To give your best on the mountain, you need to drink enough. With the 500 ml soft flask, your drinks are always within quick reach, and thanks to the convenient bite valve, you can quench your thirst immediately. The soft flask is made from durable, BPA- and PVC-free materials and can be easily filled and cleaned through the wide opening. The valve automatically seals after each sip, preventing annoying drips. The volume of the flask reduces automatically while drinking, which prevents the contents from sloshing around. The front pockets of the DYNAFIT running vests are designed to fit the shape of the flasks, ensuring they stay stable while you run.
