Great Jacket, Wrong Size

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: M

I bought this jacket as a gift for my sister - in - law and we struggled with the sizing. The body on this one was a little large for her, but it was the length of the sleeves that were a little too long.
The Jacket Fit TRUE TO SIZE off of the size chart, but since it was a gift I just ordered the wrong size.
800 fill down is great for keeping her warm in the cold UT winter. After we found the right fit it was perfect!

Perfect jacket for a serious backpacker

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XL

Looking to replace my 5-year-old Mountain Harwear down, I've tried out every down jacket on the market looking for the perfect choice and have finally come back around to Mountain Hardwear and the Nitrous. Vibrant colors, tough but attractive face fabric, two internal stash pockets, resilient elastic wrist and waist closures provide me all the technical features I need while the high-quality fill keeps the weight and the bulk down, while still keeping me warm down to 25 degrees without other layers and down to 10 degrees with a midweight baselayer. Packs down to the size of a grapefruit without a compression sack and comes out wrinkle-free every time.

My wife loves it but....

I got it for my wife for xmas. She loves the lightweight warmth of this jacket. The main problem is the size and cut of this jacket. She wears a small in every jacket she owns. The sleeves are about 2 inches too long. The shaped fit of the jacket must have been designed for a woman with no hips as it is a little snug around the hip. She loves it but wishes it fit a little more true to size

The perfect gift.

My fiancé was in need of a puffy and I decided to get her this for Christmas. The quality is awesome and noticeably better than my North Face Thermoball. The fit is great and I hear her talk about being to warm, more than I hear her talk about being cold. Looks great, very light, and great construction.

Goodbye Patagonia

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

I did a comparison with this & the Patagonia Down Sweater Jacket. A longtime Patagonia groupie, I was very disappointed by the awkward fit of this season's cut. Boxy and just plain fugly. Goodbye Patagonia, hello Mountain Hardwear Nitrous Down Jacket! I've been wearing the MH brand's jackets for years, and they always fit just perfectly. The Nitrous is no exception. Flattering & lightweight. Makes a great mid or outer layer. I'm 5'10", size 12 bottom and 10 top. M is perfect. True to size, nice color (zinc).

Disagree with above. Had to return. Wear a medium in most jackets. Runs small.

Love it!

I read the reviews of the jacket being on the large size. It fits loosely however because it is so light and not puffy it doesn't appear large. I suppose I could have ordered a medium however I am so happy with it I just had to wear it. I am 5'9" and 160 lbs and I ordered a large.

The inside pocket is large and deep (almost looks like I could tuck the jacket into itself) but it is not zippered.

The colour is great, a lovely turquoise. i wasn't sure when I ordered it if the colour would be too bright but it is just great and I have received many compliments.

sizing off

    so while i love the color (oasis blue) and feel of the jacket, the sizing is off....i ordered a medium, but it was way too big...i am 5' 9", 130lbs, 34B, just so you know, order a size down.....
