MSR's Lightest, Smallest, Fastest-Flow Microfilter

The HyperFlow is one of only 17 products awarded in 2008 with the prestigious Backpacker Magazine Editors' Choice Award for outstanding innovation in design, materials and performance.

The HyperFlow 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. Its ergonomic design, compact 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" (like Nalgene) containers - and an advanced prefilter to prolong the life of your filter.

• Ultralight: Just 7.4 oz. (209 g)
• Ultra Small: Just 7x3.5 in. ( 17.8 x 8.3 cm) makes it easy to take along even when space is at a premium
• Field-Maintainable: Can be cleaned repeatedly for flow recovery without tools
• Super Convenient: Quick-Connect bottle adapter lets you filter water directly into a variety of containers, including all MSR® hydration products and Nalgene® bottles
