Stay hydrated and keep moving — that’s exactly what the MSR TrailShot Microfilter is built for. Designed for fast-and-light adventures such as trail running, thru-hiking, fast-packing and mountain biking, this ultra-compact filter stows easily in stash pockets, bike frame bags or waist belts and deploys instantly when you reach a stream, river or lake.

With one-handed operation, you can drink directly from the source without kneeling in the mud, or pump a bottle full in as little as 60 seconds—perfect when every minute counts. Weighing just 142 g (5 oz), it meets EPA & NSF P231 standards, removing bacteria, protozoa and sediment for dependable backcountry water safety.

Unlike bulky pump systems, the TrailShot is simple to clean in the field—a quick shake helps restore flow—so no tools or teardown is required. Compact, intuitive and seriously lightweight, it’s the ideal solution for anyone who wants safe water without carrying a full filtration kit.

👉 Perfect for fast-moving adventurers who want clean water on demand without added weight.
