Backcountry Filtering

Ultralight and easy-to-use, the MSR Hyperflow is designed to change the way you travel in the backcountry.  Weighing less than 8 ounces, the filter has a compact design that's great for backpacking, overnights, or day hikes. Its tool-free maintainability makes it a safe bet on long trips where filtered water is a necessity. Its able to pump up to 3 liters of water per minute, or 1 liter every 20 strokes, and comes with a Quick Connect bottle adapter that fits all MSR bottles and a variety of wide-mouth containers.  Finally, the built-in pre-filter helps remove large particles and other bacteria before reaching the main filter to improve the quality of the water and the life of the filter.

Note: This drop has limited quantities available.
