Product Details

  • FAST & SAFE FILTRATION: Included 42MM Filter Flask Cap removes 99.99% of E Coli & Parasitic cysts. Filters approximately 1,500 liters of fresh water at a rate of>1 L per minute.*
  • HYDRATION VEST COMPATIBLE: Fits easily in most hydration vests, belts or pack pockets. Provides bounce-free stability and a flexible flask shoulder to prevent chafing.
  • COLLAPSIBLE FLASK: Soft material conforms to pockets, and shrinks as you drink to reduce movement and pack away easily when empty.
  • 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.
  • BEYOND LIFETIME WARRANTY: If you experience any issue, we’ll repair or replace the item for free. Whatever it takes to keep your adventure going.




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. Care: Avoid freezing filter. Freezing may ruin the hollow fiber membrane. If in freezing conditions we recommend you keep the filter in your pocket or near your body to prevent freezing. *Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42.
