Quick convenient filling and no plastic aftertaste - Katadyn BeFree Water Filtration System with 1L Flask

Good product for backup or primary water supply. I won't carry as much water in my pack because the Katadyn BFree lets me refill as I hike to my destination. Compact, lightweight, quick & easy hydration system without the fuss of gravity filter systems. I recommend this for hiking where natural surface water is readily available.
