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, Flux, UltraFlask or SkyFlask. Both deliver fast and easy water treatment around camp or on the go.

LIGHT & COMPACT

At only 57g, our filter is one of the lightest filter options available. Its small size takes up no extra space when stored or threaded directly onto a Seeker or Flux.

DUST COVER & HIGH-FLOW NOZZLE

Keeps dust off your drink nozzle. Quickly open and close the drink nozzle with one hand without any direct contact with dirty hands.

42mm THREAD COMPATIBLE

Thread the filter onto most popular backpacking water storage bags, flexible bottles and running flasks including the Seeker water storage bags, Flux bottles, UltraFlasks and SkyFlask handhelds.
