Its ergonomic design, diminutive size and tool-free maintainability make it just as appropriate on day trips as it is on multi-day excursions. Also included is a Quick Connect Bottle Adapter allowing direct connection to all MSR hydration products and a variety of other wide mouth containers (63mm threaded openings) such as Nalgene. An advanced prefilter to prolong the life of the filter is included.

The HyperFlow pumps more than 3 liters per minute or one liter every 20 strokes. Its small size makes it easy to take along even when space is at a premium. Can be cleaned repeatedly in the backcountry for flow recovery without tools. Over-molded grips give excellent ergonomics and pumping comfort.
