LifeStraw

Mission

LifeStraw's Mission filtration system isn't what you want to bring backpacking, but if you're setting up your car camping spot or planning on spending a week hunting or fishing from basecamp, it's just what you need. The 12- or 5-liter roll top bag is easy to fill from the nearest stream, river, or lake, and the gravity-action filter makes cleaning your water easy as doing nothing; just hang the bag up from a tree and Newton's best friend will pull the water through the 0.02 micron filter, sucking out bacteria, protozoa, viruses, and sediment. The bag is BPA free, and the filter will last for 18,000L, which is probably more than you'll ever be able to drink.
