Performance
Fast flow rate. Zero pump. The BeFree’s hollow fiber filter gives you clean water straight from the stream — at up to 2 liters per minute. The soft Hydrapak flask collapses flat when empty and tucks anywhere. Great for fastpacking, travel, or emergency kits. The filter handles murky sources, and the wide mouth fill design is smart in the wild. Bonus: the black edition doesn’t scream “outdoorsy” — it blends into an urban pack like it was built for it.
