Lightweight, lofty protection.

Weighing less than a pound, the Mountain Hardwear Men's Nitrous Down Jacket provides serious warmth without the weight.

Q.Shield's treatment helps the down retain its loft for water-resistant protection, and the Nitrous Down stuffs into its own pocket, so feel free to take it on all your skiing, climbing, and backpacking endeavors.

Yes and No

  • Familiarity: I've used it several times
  • Fit: Runs large
  • Height: 6' 0"
    Weight: 175 lbs
    Size Purchased: L

The jacket is awesome - great color (green) weight, warmth, material, etc. Kept me warm walking around in 15F Colorado nights with only a t-shirt under. And the ability to stuff into a pocket works great as a backpacking pillow. Its tough to complain about it, the lack of a 5-star is only due to the sizing/fit issues. As many others have said, the fit is oddly large in places. I'm 6'1 180, athletic and the size L does not fit right (however my L ghost whisperer is perfect). Its enormous in the waist/belly and upper arms, however the chest and lower arms are OK.
Maybe others have the proportions to pull this off, but I certainly dont, which is disappointing because its a nice piece.

Great jacket...

  • Familiarity: I've used it several times
  • Fit: Runs large
  • Height: 5' 8"
    Weight: 154 lbs
    Size Purchased: Medium

This jacket is light, warm, and stylish. The fit is a little large, but not huge. I'm 5'8'' and 154 lbs, athletic build. I ordered a medium and am very satisfied, but if you want a form-fitting jacket, maybe order a size down or a different brand. The bottom of the jacket hits at the hip, not the waist, which gives a little extra warmth. I do agree with other reviewers that the zippers do not seem to be very high-quality, but it wouldn't prevent me from recommending this jacket.

Beautiful jacket but.......

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs large

Great looking and love the Mountain Hardware products but hoped for something more. 5'9" and 155 lbs,. arms were fine but jacket a little long. Wore it once, 30 degrees and windy with turtle neck underneath; froze. I just needed something warmer especially for the money.

A tall guys Godsend

  • Familiarity: I've used it several times
  • Fit: True to size

Ironically, the big reason I've noticed this coat getting bad reviews is the reason I adore it. I'm 6'4 and a fit 220, this coat fits amazing. I bought a North Face down coat as a Large and it just wasn't cutting it for arm length. I bought a MH Conduit coat last year and it fit my arms, so I decided to buy this and give it a shot. It fits perfect! The arms are long enough and finally I own a nice down layer that is long enough not to bunch up over top of my fleece under layer. The material is a little thin, I was hoping to use it for spring rock climbing but I'll probably pass on that. On the other hand, how are you supposed to keep the weight down at this price point? I ordered it knowing the material wasn't going to be heavy. It folds into it's pocket for a perfect fit in my mummy bag for a pillow.
As a side note, it's super stylish also and looks great around town. You literally won't even notice you're wearing it until you take it off and realize how cold it is without it!
I'm leaving for NY to backpack along Lake Erie tomorrow(-2 degrees for the high) and will be using this as my main layer underneath my shell and have no worries about warmth.
Thanks Mountain Hardwear for finally making a coat I can wear!!

Nice, but NO dice!

  • Familiarity: I returned this product before using it
  • Fit: Runs large

Awesome light weight jackect with nice features. Fit...not so much. I wear a 42R suit. The size large fit great in shoulders and arms, but was huge in the waist and very long. Not a very efficient way to keep warm.

Ridiculous Warm

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I went with the Nitrous over the Ghost Whisperer because of price and the lack of super shiny material. And really, whats a few more ounces?

This jacket is super warm. Haven't been able to test it out in really cold weather yet. But in the 30's and 40's, I'm comfortable with this jacket over a t-shirt.

My only complaint is the fit. I'm 6'0'' and 175 with an athletic build. Ordered a medium. The jacket is a little bulky in the stomach area. But other than that - it fits great.

I see two different pictures for this jacket. One picture has a chest pocket and the other one doesn't. Can you confirm if the Shark/State Orange color jacket has a chest pocket?

Responded on

Yes, the Shark/StateOrange jacket does indeed have a chest pocket. Here is the correct image for that Color-way.
