I just recently graduated from college and a family member bought me the Sawyer Squeeze Water Filter. I saw an ad for it in Backpackers and it looked solid, but I never thought about it again until I received it as a gift. Anyone else using this cool filter? I've only used it once and that was on a dayhike and my first reaction was it could take a while to fill up the pouch if you are not in swift waters. Also, your hand could get freezing cold during the cold months. They have a lot of maintenance in order for it to last as long as advertised, but I guess that the tradeoff to having a 3oz water filter. lol. I really like it and it is a great gift. I still haven't figure out how my relative thought I might like a new water filter and picked out a very lightweight one!
