This extra-large AutoFlow gravity filter system from MSR delivers 10 litres of clean water fast while you set up camp, prep dinner or relax. And its big capacity means fewer trips to the river to haul the water you need. Similar in packable size to the 4L version, the AutoFlow XL system's durable flat base doubles the water volume for only 340 g (12 oz) of total weight. Ultralight and supremely packable, it offers the luxury of pump-free group filtration for basecamps, scout troops, horse packers and other backcountry groups. And just one 10-litre fill of the reservoir can supply 1-2 people with a whole day's worth of clean water.
