HydraPak Ultraflask + Flask Filter System

HydraPak UltraFlask + Filter System – Safe Water, Anywhere on the Trail

The HydraPak UltraFlask + Flask Filter System is built for trail runners, ultra athletes, hikers, and fastpackers who need lightweight, reliable water filtration on the move. Combining a compressible soft flask with an integrated high-performance filter, this system allows you to refill from natural water sources and drink safely without carrying excess water weight.

Designed for efficiency and speed, the UltraFlask collapses as you drink, reducing sloshing and pack bulk. The integrated filter removes bacteria and protozoa from backcountry water sources, making it ideal for remote trails, multi-hour efforts, and long ultra-distance events where aid stations may be limited.

Lightweight, compact, and easy to use — simply fill, squeeze, and hydrate. Whether you’re racing 100km, hiking alpine terrain, or exploring off-grid routes, the UltraFlask + Filter System gives you freedom to move further without relying solely on carried water.
