LifeStraw Steel

No need for carrying large amounts of water or filtration systems the next time you’re backcountry hiking or backpacking: one nine-inch long, 4.2 ounce LifeStraw Steel is all you need to make river and stream water safe and drinkable. The straw features a two-stage filtration process, including a 0.2 micron hollow fiber filter and an activated carbon capsule, that rid water of 99.9999% of waterborne bacteria, 99.9% of protozoa, various chemicals, and bad tastes. Each is good for filtering 264 gallons (1,000 litres) of water on the fly, no batteries, pumps, or additional effort required.
