Hydrapak HydraPak Filter Cap (42 mm)

Filter water on the go. The new 42 mm Filter Cap threads seamlessly onto all sizes of HydraPak's 42 mm 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.
