Gravity, the physical law and culprit behind heavy packs and tired shoulders, has never been a backpacker's friend. Katadyn has now shown us that gravity isn't all that bad. The Katadyn Base Camp filter uses nature's force to microfilter water anywhere. Simply fill up the included 2.6-gallon bag and hang it from a tree. Gravity will take care of the rest. No pumping involved, leaving hands free to set up camp, lead a route or apply Icy Hot to those shoulders. The Base Camp is a member of Katadyn's exclusive BackCountry Series.The Base Camp's cleanable Hiker PRO cartridge removes Bacteria, Giardia and Cryptosporidium to EPA standards and the Activated Carbon Core reduces unpleasant tastes and odors from the water.
