Lighten your load and drink right from the source. Hydrapak took their go-to flask and added filtration to create a system that delivers hydration without contamination. The filter — light and compact — screws on top so you can drink right from the flask. Or — if you’re carrying more water — use the system to fill a bottle or reservoir.
INCLUDED BACKFLUSH ADAPTER: Plugs into filter valve and threads onto a HydraPak Stow or bottle of clean water for backflushing the filter to restore its flow rate.
VEST PACK FIT: Soft material conforms to most hydration packs and larger vest pockets for a secure and stable fit.
- The integrated filter removes Escherichia coli bacteria, Cryptosporidium parvum cysts, and Giardia Lamblia from approximately 1,500 litres of water at a rate of >1L per minute.*
- Minimal design and lightweight materials make this filter the ideal choice for runners. It takes up no extra space when stored or threaded directly onto a flask.
- Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.
