Rated 5 out of 5 by from Perfect little pocket filter This little guy is awesome. Fit into an inner pocket in my carry-on, then in a jacket pocket when we got to our destination. I used it to filter glacier water in Iceland. It probably didn't, strictly speaking, NEED to be filtered, but ya never know. Popped this bad lad into a pristine, flowing stream, pumped for a minute or two, and had a Nalegene full of cold, clear, clean water. I'd definitely recommend this to anyone who wants something fast and dummy-proof. 13/10, would filter again.

Rated 5 out of 5 by from Trail Shot This filter is so easy to use, primes quickly and pumps fast. It works well to drink directly from the spout or fill a water bottle. The filter is easy to clean and replace.

Rated 5 out of 5 by from awesome Just took this on a 40 some mile backpacking trip and it was wonderful! We own a Miniworks Ex which we have used for years, but this is just so much lighter and more compact. I can foresee using it on bike packing trips and will definitely be packing it in for day hikes, which is something I rarely did with the Miniworks. Will be part of my 10 essentials prep. Excellent flow rate - the Nalgenes filled up very quickly, and I enjoyed having the extension tube - I couldn't imagine using some kind of straw or other awkward device where you have to be right at the water level. I do have some carpal tunnel in one of my arms right now, so I had to do a little bit of switching hands to squeeze, but didn't find it too aggravating. Just got a Reactor stove as well, and between how fast this filter purifies water and how fast the Reactor boils it, camp chores have been super sped up- couldn't decide whether the stove or the filter was the MVP for this trip! You're killing' it, MSR!

Rated 5 out of 5 by from Most important item in the backcountry! I use the trail shot for long days on the bikes and carry only two bottles to keep weight down. It does a great job filling bottles in an efficient manner and I'm back on the bike for more sMILES!

Rated 4 out of 5 by from Fast and Easy I purchased this for times when I want something fast for an approach and the like. This really fits the bill. I don't have to carry an extra liter, just a couple squeezes of the hand and I have what I need. This thing is great!

Rated 5 out of 5 by from Ease of use I used my TrailShot on Washington Trail Association work parties for several months but lost it somehow last weekend working in the Methow Valley but I'll purchase another TrailShot shortly. What I like most about it is the ability to carry less water and keep refilling my water bottles as needed on trail work parties. Have enough weight to carry without a heavier filter or lots of water bottles. It takes up little room so it goes with me whether I think I'll need it or not.

How do you know when the filter has reached its maximum cleaning capacity to operate at full functionality? Also, can you/should you backwash the filter?

Asked by: Dean
Hey Dean, Thanks for the question. You can backwash this by shaking it! As for checking the filter, MSR recommends doing the following steps to check it's functionality: 1. Hold the filter at about 45° and prime it by squeezing the Bulb (G)10 times. 2. Pump 3/4 liter of water into a bowl or pot. 3. Unsnap the Prefilter (M) from the Female Check Valve Housing (L) (put it in a safe spot). 4. Unscrew the Female Check Valve Housing from the Male Check Valve Housing (J). 5. Remove the Check Valve (K) and reverse its direction. Place it back into the Female Check Valve Housing. 6. Screw the Female Check Valve Housing back onto the Male Check Valve Housing. 7. Remove the Spout (B) and Umbrella Valve (C). 8. Place the Cap (D) into the bowl/pot of clean water and pump 1/2 liter of clean water backward through filter. 9. While the Cap is still submerged, squeeze and hold the Bulb. Then remove the Cap from the water and release the Bulb. 10. If Bulb re-inflates within 30 seconds, the filter is NOT SAFE. (NOTE: If a few bubbles escape the Check Valve, unscrew the Female Check Valve Housing, reseat the Check Valve, and screw the Female Check Valve Housing back onto the Male.) Then test the filter again. 11. If Bulb stays compressed, the filter is safe to use.

How to store for the season?

Asked by: Seabreeze
Thanks for the question! Below are the pack & storage instructions for your filter. I also included a link to the manual. Hope this helps! 1. Remove Prefilter from water. 2. Squeeze Bulb to purge excess water. 3. Replace Clean Side Cover. 4. Before long-term storage, remove Filter Cartridge (See “Replacing the Filter Cartridge”) and let Bulb and Filter Cartridge dry out at room temperature for at least one week. 5

It is "field cleanable to restore flow" - but does the filter ever need to be changed? If yes, how much are they?

Asked by: Dave
Hi there Dave! The MSR Trailshot's filter does need to be changed after filtering 2000 liters of water. We do carry the replacement filters: Happy hydration!
