Ideal for longer expeditions like ultra events or trail running, the XA FILTER CAP 42 filters bacteria and protozoa from natural water sources, so you can drink easily and safely without needing to carrying huge volumes of water.
42 mm Filter Cap is compatible with HydraPak flasks.
Filtering your water on the go means you can carry less water, and therefore less weight, while you run to help reduce fatigue.
The cap removes bacteria and protozoa from approximately 1500 liters of water to help keep you hydrated and healthy, however remote your destination.
The cap is compatible with all Salomon soft flasks with a 42MM opening (purchased from spring 2020 onwards).
