Mountain Hardwear Men's Nitrous Jacket

Warm and light
Used the Nitrous Jacket on a week steelhead fishing trip and was very pleased with it. It is so light you hardly know you have it on, and it is very warm. I used it as a layer underneath a wind/waterproof fishing jacket and over a capaline long-sleeve tshirt and it added a lot of warmth without any bulk. Morning temperatures were in the mid 20s and I was toasty. I am 6'2" tall, 225 pounds with a bit of a belly and the fit was form fitting, but not tight. I would say it is smaller than a normal XL size in the torso but the arm length and jacket length were just fine. Liked it so much I'm thinking about getting one for a family member for Christmas.

Great Spring/Fall Jacket
I just got this jacket the other day and absolutely love it already. Fall can't come soon enough. This jacket is going to be perfect for the trail in mid Oct. I was really surprised how well a large fits as I'm 6'0'', about 175lbs. Usually I would need an XL for the sleeve length, but then it's too bulky in the chest. Very happy with a large. You can't go wrong with this jacket.

Great Down Sweater for the Slim
This is an excellent down sweater for those with a slimmer physique. I am 6' tall and 165lbs, and the medium fits me very well. It's nice to find a down sweater that is sized for those that are a little more lean. The body and sleeves have nice length to them, without having the cut through the body be too big and boxy. As usual, the quality from Mountain Hardwear is top notch and the jacket packs down into it's own stuff sack, practically disappearing it is so compressible. Not a single complaint about this jacket....excellent quality, very compressible while still retaining good warmth, and most of all, sized nicely for those of us who are a little slimmer.

excellent lightweight warmth
very light-weight, great fit and warmer than expected. I would only change 2 things (both of which would add weight): 1. add zippers to the hand warmer pockets 2. use a goretex-type waterproofing laminate on the exterior even without those changes, it's still an excellent light layer, easily packable and surprisingly warm.

Best Purchase Ever
For an 800 fill down jacket this is perfect in terms of space. Very thin, yet very warm. Perfect for many conditions. Excellent! I don't like just one thing- periodically small feathers go out of the jacket!
