Filtering water on the go. The new Hydrapak 42mm filter cap screws seamlessly onto all sizes of HydraPak Seeker 42mm threaded water storage bags and flexible Flux bottles, transforming them into filtration solutions. The end result is lightweight filter kits that can be used either to squeeze filtered drinking water into other camping bottles and containers or to drink freshly filtered water from a Seeker or Flux. Both allow for quick and easy water purification at camp or on the go.
