As easy as it gets! Simply scoop the Katadyn BeFree pouch into the nearest stream or water source, screw on the filter cap, and drink straight from the bottle or filter into one of your own. The filter works in real time, with no waiting around for your water to be clean. When not in use, the pouch rolls up into a small profile for easy storage in your pack.

The filter threading is also compatible with a variety of Hydrapak products, so carrying a larger volume container is great to have around camp, when you’re done with your miles for the day.
