It filters water at over 1 liter per minute, fits snugly in hydration vests or pockets with bounce-free stability, and includes a backflush adapter for easy filter maintenance. Lightweight and durable, it’s designed for hiking, running, camping, and travel, backed by a lifetime warranty to ensure reliable hydration wherever your adventures take you. ## Description 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.
