MSR TrailShot Microfilter

From ultralight backpacking trips to epic mountain bike rides, the MSR TrailShot Microfilter provides ultra-compact purification, allowing you to drink directly from streams and lakes on the trail. Tipping the scales at a mere 5. 4 ounces, the TrailShot tags along in your pack without the bulk or weight of traditional water filters. The one-handed pump action efficiently filters water of common contaminates, including bacteria, protozoa, and suspended particulates. When it's time to clean the filter itself, simply shake it a few times and get back to filtering water from the stream or lake. It treats up to 2,000 liters of water before requiring a replacement and cleans one liter of water in a mere 60 seconds.
