VEST COMPATIBLE FIL TRATION
Lighten your load and drink right from the source. We took our 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.
FAST & SAFE FILTRATION - The integrated filter removes Escherichia coli bacteria, Cryptosporidium parvum cysts, and Giardia Lamblia from approximately 1,500 liters of water at a rate of >1L per minute.*
SECURE GRIP - A flexible and structured grip makes it easy to hold the flask while screwing and unscrewing the filter.
VEST PACK FIT - Soft material conforms to most hydration packs and larger vest pockets for a secure and stable fit.
HIGH-FLOW - Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.
LARGE OPENING - 42mm opening lets you fill the flask easily at any water source.
COMPRESSIBLE - Flexible design shrinks as you drink, minimizing water movement.
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. *Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42.
