As Advertised

I just got this jacket and so far ... so good. Haven't run in anything below 45 degree's but it was sprinkling on that run and this jacket worked as advertised. It seems to hold heat well while warming up and then bleeds it off after you come up to mid work out temp. The pic I attached is with the hand warmer / gloves tucked in but these are a very cool feature. One less thing to carry. The breast pocket is big enough for a Nano, credit card and car key. There's a pocket on the inside but it's directly underneath the outside pocket. If you were to put anything in both, it would get a little bulky.

Outstanding active jacket

  • Gender: Male
  • Familiarity: I've used it several times

Wish I had this jacket years ago. Works perfect for a running jacket. A little cool at first but once you start running you warm up without overheating. The back side of the jacket does a great job of venting excess heat away from you. Front pocket fits an iPhone 4 with case sideways perfectly. At 6' 190, wide shoulders, large fits perfect.

One of a kind

I've had this jacket for a few months now and used it for winter/cool weather running as its primary use and it's double thumbs up for performance and fit. I'm 6'4", 205 and the XL fit great with a bit of room underneath without being baggy. The front face fabric keeps out any wind while the back breaths extremely well. I used to run with light gloves, but more often than not I remove them now thanks to the half-glove cuffs as well as the uber long sleeves (I wear a 36-37" dress shirt sleeve) fit even my long arms. Thumb holes actually work and are comfortable. The only thing I'd change would be to take the zipper all the way to the bottom of the jacket, as they've left it about 1/2" up from the bottom. Pretty minor really. This jacket also is great for X-country skiing and I've used it for spring ski touring on sunny days when a softshell is too much but a single shirt isn't enough.

Question about the material. Here on...

Question about the material. Here on the material is listed as DryQ Active, but on the MH website it is listed as "AirShield Active," not the DryQ Active; however, DryQ Active IS listed as a technology for this piece on the MH site. My question is this: what material is used in this jacket (as least the front facing material)? And if it is AirShield Active, how does that material compare with the DryQ Active?

Thank you for the help!!

Responded on

This item is made with Airshield Active, NOT Dry.Q as Backcountry suggests. The product I received does not list Dry.Q Active anywhere on the jacket or the tags, only Airshield Active. When I emailed Backcountry, they replied to me as if I didn't know how to access websites or read tags/labels on PHYSICAL PRODUCTS., and assured me the PICTURES they've seen say its Dry.Q Active. However, MH's website and MY product I received clearly state Airshield Active as the only technical feature used in this jacket.

With that being said, the jacket is very nicely constructed and fits very close to the body. I am 5'6", 155 lbs, stocky but muscular, and the small fits me with only enough room for a compression shirt underneath, which is what I wanted. What sold me on the product, however, was the promise of Dry.Q Active, which this product does not have.
