Not clammy!

I have several different running jackets and hands down, this is the best for dumping rain. Recently, we've had a some real downpours in the Bronx and these presented a good opportunity to try out the new jacket. It was quite comfortable. I think I might have preferred a size smaller, but it fit nicely overall. The hood worked very well. Didn't slip off my head and provided a little shielding from the pelting rain. Inside of jacket didn't get overly steamy or clammy. Outside shed the rain perfectly. Got the jacket to late to try in super cold weather.

PNW Requirement!

This jacket should be mandatory for any outdoor athlete in the Pacific Northwest. I bought it primarily for running in the cold and rain during our long winter/spring months. I was worried that it wouldnt be breathable enough given that it is fully waterproof. So far I have been very pleased. Yes, you might get a little damp from sweat when pushing it up a hill, but compared to many other running jacket I have, this is much better.

I like how its waterproof, but doesnt stick to your arms after getting wet like other wind breaker type jackets that I have. It also has tapered sleeves which is nice for minimizing excess material. I sized it to fit with just a short sleeve wicking layer underneath since its primary function will be a running/biking jacket. I'm 5'10" 150lbs and got a medium. It fits perfectly for what I got it for. Feels a little snug with a long sleeve baselayer under, but I dont plan on ever needing a long sleeve underneath. I would have sized up if it was just a casual jacket. I also like the lack of bulky pockets. I dont need handwarming pockets when Im running or biking. I also like how this jacket doesnt come with the attached "gluff" (glove/cuff) like the non-hooded jacket has. I'd rather bring my own gloves if i need them and decrease the bulk at the end of the sleeve.

My only grips: sleeves are a little long, as with a lot of MHW product i try, maybe i have short arms. Second, I would have like either some velcro at the end of the sleeves or a more elastic cuff to keep the sleeve locked down. Minor annoyances with an otherwise flawless jacket. I also dont usually use a hood will running or biking, but its come in handy a few times so might as well keep it just in case.

Bottomline: This jacket enables me to train year round, stay out longer and keeps me happy. A worthy investment for anyone putting in work while in wet, windy, cold conditions.

Good biking jacket

I discovered this coat at a store that was marketing it as a biking jacket, and bought it from BC for such. I think it works really well: the seams are flat enough that the hood can go under a helmet, the softshell nature of DryQ means it is nice and quiet, it is very trim and doesn't flap in the wind, but is stretchy enough to insulate under.

I'm 5'8" and 165 lbs and wear a medium. It's trim but works well for my purposes.

Don't Know What you Got (Till It's Gone)

Just returned from what should have been a fantastic trail run at the syncline in WA. Unfortunately, I return broken hearted as my MHW Effusion Jacket liberated itself from my running pack somewhere between mile 2 and 7, and no amount of backtracking and desperate begging other trail users could turn it up.

I already miss my Jacket terribly. In less than a month it had become my goto shell, comforting me on sloppy/sleet-soaked trail runs of several hours in the Gorge, hugging me on the ups and downs of split-boarding excursions on Hood, slipping out for morning training runs, and even hanging around the pad. It hadn't even started to smell yet.

It never got clingy or uncomfortable, sure occasionally things heated up and got a little steamy, but it always breathed through those breathless moments and I never felt like I had to get it off of me right after like all the others; I'd often just bask in the afterglow of my blaze orange shell.

Did I mention this thing was absolutely, completely water proof? And the hood fit like it had been tailored for me specifically, just like the rest of the jacket? Oh, and when the hood was down, the fabric, so soft and supple, just fell down around my neck and sat there like a collar. It was so close to perfection. Sure it doesn't have multiple pockets like the description says, & the pocket it does have down on the hip could have been placed on the chest, I might have preferred that, but that's just nit-picky.

I miss you MHW Effusion Hooded Jacket. I dedicate this review to you. And this song:
Please come back to me. Ouray won't be the same without you.

Half-gloves?? Does this jacket have the same half-gloves as the non-hooded version? If not, does it have thumb-holes at all, or is it a normal cuff.


Responded on

It should have the same cuffs as the non-hooded version.

I hope so. Those half gloves are genius! Thanks for your help!

Responded on

No, it does not have half gloves or thumb holes.

This jacket is sweet for very cold running, but I wear it every day I backcountry ski. It's the perfect jacket for skinnning uphill where you are working hard but still need some winter protection. It's light and it breaths just enough while keeping you warm. I just throw a puffy or a shell over it at the top for the ski down. It's THE integral piece in my setup. Get one!
