What Our Gearhead(R) Experts Are Saying:"I bring the 3. 0L BeFree on group trips where I want one system handling water for the whole camp - fill it at the source, hang it at the site, and it's ready by the time dinner is. At 3. 5 ounces, it's one of the lightest setups for the volume it covers, and the EZ-Clean Membrane keeps it flowing trip after trip."Good camp mornings start with coffee, and coffee starts with clean water. The Katadyn Gravity BeFree 3. 0L Microfilter handles that quietly - fill the collapsible reservoir at the source, hang it from a branch or trekking pole, and let gravity do the work while you set up camp or break down a site. At 2 liters per minute through a 0. 1-micron hollow fiber filter, it moves fast enough that waiting rarely feels like waiting. The EZ-Clean Membrane clears field debris with a simple shake or swish, the 3L capacity covers a group without repeated trips to the water source, and the whole system packs down to 3. 5 ounces. From weekend car camping to extended backcountry trips, it's the kind of gear that earns its spot by staying out of the way.
