This is a favorite among a few GearJunkie staff for its ease of use and packability. In our review, we noted, “The BeFree is basic filtration. You just fill the bottle with water and drink. It takes very little pressure to pull water through the filter tip, and thus you can kind of squeeze the very pliable HydraPak SoftFlask bottle and blast water into your mouth, or suck water through.”
We use it hiking, backpacking, fishing, climbing, etc. It’s a solid product that would make a surprisingly useful gift.
