There didn't seem to be a "gear" board so placing this here: Has anyone tried the Sawyer Squeeze filter system and its in-line system for hydration bags? I'm thinking of getting one since I saw the Propsters from Backpacker mag's Get Out More team talk about them at a seminar a few months back. Right now I use a Katadyn Hiker Pro / steripen but if the Sawyer works as good as I hope it does I might ditch the Katadyn to dramatically cut weight in my weekend bag.
