Mammut Soft Flask

The ideal hydration system for those who want to do without unnecessary weight. The robust Soft Flask from HydraPak made of 100% PBA- and PVC-free materials withstands freezer temperatures, but can also be filled with hot drinks. Thanks to the high-flow silicone bite valve, you can quench even the worst thirst. The bottle contracts as you drink, so only take up the space its contents need, so fits perfectly in any running vest or backpack for light-footed adventures.
