Product details

The TrailShot™ Pocket-Sized Water Filter by MSR is small enough to hide in a stash pocket and deploy quickly, allowing the user to easily drink from sources along the trail for easy hydration. One hand and sixty seconds is all that’s needed to filter a liter of water, making this filter an ideal option for fast-paced, high-mileage adventures.

Key Features:

  • Lightweight – At only 5oz, the filter can easily be tucked into a small pocket, taking up little space.

  • Instant Hydration – The long tube allows the user to drink directly from the source, or to refill a hydration reservoir with clean water.

  • EPA Drinking Water Standards – The filter is effective against bacteria (99.9999%), protozoa (99.9%), and particulates (dirt, microplastics). It meets the Environmental Protection Agency (EPA) standards as well as the NSF Protocol P231 testing standard for removal of bacteria and protozoa.

It's great to attach to your pack directly, saving you from having to fill up a water bottle every time.
