Katadyn BeFree Gravity 3,0 l

With the ultra-lightweight and compact Katadyn BeFree Gravity 3.0 l Hanging Water Bottle with open hollow fibre cartridge, you no longer have to worry about where you're going to drink next. Simply fill the soft plastic bag through the wide opening and the EZ-Clean Membrane™ filter takes care of water purification. Filtration is carried out by light pressure. After use, clean the filter cartridge by filling the bag only about halfway with water, closing it and shaking it, or the cartridge can be removed and rinsed in a lake, river or stream. The bag can be simply rolled up to take up as little space as possible.
