The Ultimate Ultralight,
Pocket-Sized Water Filtersee features
Ditch the weight.
Built for fast-paced adventurers - like trail runners, hikers and mountain bikers - the all new TrailShot backcountry microfilter delivers the clean water you need all day, in a solution that won't slow you down.
Ultralight & Compact
So small, there’s no excuse to leave it at home, this tiny filter weighs a mere 142 g (5 oz) and fits in the stash pockets of your gear.
Drink from the Source
Its smart spout lets you drink directly from sources along the trail, and refill your bottles with clean water for later on.
Hollow Fiber Technology
Tiny pores in the fibers allow water to pass through but trap harmful protozoa, like giardia and cryptosporidium, and bacteria, like salmonella.
“The MSR TrailShot eliminates all excuses to leave your filter behind.”
“I see thru-hikers, ultra runners and avid adventures who like to get out there adding this piece to their quiver.”
“Such innovations—like the Guardian’s self-cleaning filter, or the TrailShot’s hand-held size—are not possible without shifting your way of thinking from conventional, pre-existing products.”
“The new TrailShot pocket-sized water filter was designed for quick and active adventures. So it was no surprise that the MSR TrailShot is also ideal for weekend and overnight backcountry bikepacking trips.”
Tested: Meets U.S. EPA drinking water standards* and NSF protocol P231 for removal of bacteria (99.9999%), protozoa (99.9%), and particulates.
Pocket-Sized & Light: Like small water bottles, energy chews, mini bike pumps, and tubes, this 142 g (5 oz.) filter disappears in stash pockets.
Instant Hydration: Drink directly from the source—without lying in the dirt—and refill your bottles or hydration reservoir with clean water.
Quick-Deploy: Zero set-up and simple one-handed operation fills 1-liter bottles in 60 seconds.
Simple to Clean: A few shakes helps restore flow rates in the field; no tools required.
