42mm Filter Cap

HydraPak

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 end result being lightweight filtration kits that can either 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 57 grams, 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 opens and closes 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.
