Sawyer Products SP129 Squeeze Water Filtration System
The Sawyer Squeeze SP129 is the most trusted backcountry water filter on the market — and for good reason. Its 0.1-micron absolute hollow fiber membrane removes 99.99999% of bacteria (including salmonella and E. coli) and 99.9999% of protozoa (giardia, cryptosporidium). The kit includes two 32-ounce BPA-free squeeze pouches, a drinking straw for drinking directly from water sources, and a hydration pack adapter that threads onto most reservoirs. Rated for up to 100,000 gallons with proper backflushing, this is a lifetime water filter that weighs just 3 ounces.
