This extra-large AutoFlow gravity filter delivers 10 liters of clean water fast - all while you set up camp, prep dinner or relax. It's big capacity means fewer trips to the rive to haul the water you need. Similar in packable size to the 4L system, the AutoFlow XL system's durable flat base doubles the water volume for only 340g (12 oz) of total weight. Ultralight and supremely packable, it offers the luxury of pump-free group filteration for basecamps, scout troops, horsepackers and other backcountry groups.
