Katadyn BeFree 1.0L Water Filter (Black)

The Katadyn BeFree pairs a 1.0-liter collapsible soft flask with a fast-flow 0.1-micron hollow-fiber filter that removes bacteria, protozoa, and microplastics. Drink straight through it or squeeze into a bottle. The flask rolls flat when empty, and the filter cleans in the field by shaking, no tools or backflushing. Blacked-out 1.0L version.
