Katadyn BeFree.
Collapsible 1L flask with an integrated 0.1-micron filter. The fastest-flowing squeeze filter on the market — drink directly from the source in seconds.
The Verdict.
Gavler Meta-Score
“The fastest, most intuitive squeeze filter available. Fill and drink — no hoses, no pumping, no backflushing. Flask durability is the tradeoff. Best for day hikes and weekend trips; carry a spare flask for thru-hikes.”
