LifeStraw Peak Series 8L gravity filter and 8L safe-storage bag, complete system for group hydration at basecamp, in an RV or on the trail. Two fully leak-proof 8L bags provide a dirty-water reservoir and a safe water storage with easy-pour screw-spout and hose attachment. The re-engineered 0.2 micron membrane microfilter removes bacteria, parasites and microplastics, and is designed to resist clogging from sand and silt. Use the filter inline for gravity filtration, remove it to drink as a straw, connect to a bottle, or cap the bag to use as extra storage. Made from premium, BPA-free FDA-approved materials resistant to punctures, the microfilter lasts up to 2,000 L — water will stop flowing once the filter reaches end of life. System includes 1.2 m hose, quick connector, carabiner, leak-proof cap, carry strap, backwash accessory and user manual. Dimensions: dirty bag 35.6 x 59.7 cm, safe bag 35.6 x 59.7 cm, total weight 1,170 g.
