Filter water on the go. The new 42mm Filter Cap threads seamlessly onto all sizes of HydraPak’s 42mm threaded Seeker water storage bags and Flux flexible bottles, morphing them into filtration solutions.

The result is a lightweight filtration kit to decant into that can be used to squeeze filtered potable water into other camp bottles and containers, or to drink freshly filtered water from a Seeker. Both deliver fast and easy water treatment around camp or on the go.
