Katadyn Hiker Water Filter:
Way back in 1994 Backpacker Magazine declared the PUR Hiker water filtration system to be "the unrivaled best in terms of field use." Those of us on the staff who bought these things years ago still use them (most of us have new replacement filters now). The PUR Hiker water filtration system's high output and low maintenance design is so good that the 22 product comparison testers for Backpacker Magazine gave it the highest rating in every category tested. The intuitive pump design and the included extra touches like the prefilter and universal water bottle adaptor cap--stuff you have to pay extra for with other water filtration systems--makes it an easy choice for seasoned backpackers and fresh newcomers.
