Perfect compact water filter - Katadyn BeFree Water Filtration System with 1L Flask

I have the 5L for filling up water and keeping it at camp. This 1L is perfect size for keeping on you at all times. It i reliable and really easy to use. It barely takes up any space when empty and a lifesaver when you need it. Its ideal for places that have readily accessible water so you don't have to stock up and can always resupply. Sometimes I take it up for long multi-pitch climbs as the descent will often have water sources. Really cuts down on weight!
