The MSR HyperFlow Microfilter utilizes the latest Hollow Fiber Technology in a package so small and so easy to use it will change the way you travel in the backcountry. Designed for the backcountry the MSR HyperFlow pumps more than 3 liters per minute or one liter every 20 strokes and is so lightweight at 7.4 oz that is sure not to weigh you down. MSR HyperFlow Microfilter's 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. An advanced prefilter is included to easily remove the big particles before entering the HyperFlow to prolong the life of your filter. The MSR HyperFlow Microfilter is the convenient, lightweight, fast pumping water filtration system that comes complete and ready to hit the backcountry trails.
