I love this jacket

Warm. Stylish. WARM.
I fits a bit snug around the hips and under the arms but I'll take it if it means it keeps more of the cold out! The only thing this puppy lacks is zipper hand pockets.
Great product.

Great buy

Simply put, the best fitting down/jk I have tried on. 6'3" 190 (L), this brand has the best fit for tall lean guys.Athletic fit.
tried on several brands, this jacket was lighter and warmer than most I tried on for a thin 800 fill.

F10 Nitrous is the best in the line.

Excellent jacket, great features, compressible and warm. The material can be a little prone to snagging, then again a material that light weight will inherently have a trade off. The chest pocket is awesome. It sits high enough that it is not pressing the contents directly against the chest, and is easy to access from under a hard shell without fully unzipping the content. The included stuff sack is a nice touch. This should be an essential gear piece in every outdoor enthusiasts closet.

Pretty much normal

800 fill down is quality and warm, this jacket works great as a stand alone in moderate temperatures (15-30ish degrees), works even better as a mid layer under a shell. The hand pockets do not zip, and can get caught on things if you're not careful. Material is a little thin, and should be used under a shell for anything but hanging out around camp. The fit definitely athletic, and look to the Patagonia down sweater for a roomier fit. Definitely a good investment. Packs down super small too

Great Jacket!

A great jacket. Works great as a mid-layer. I have really long arms, and the XL is a perfect fit. Super warm, and very packable, and it comes with its own stuff sack!

super warm

this thing is made well and with obviously the highest loft down you'll really see in a down jacket. only complaint is the no internal pocket. but all in all its a super comfortable, super compressible, super warm jacket at a good price.

Love the jacket! They run small

I'm only giving this jacket a 4 star rating because the sizing is a little strange. I am 5'7" 185lbs and the large is quite snug on me. I kept it because the XL is too loose. Mountain Hardware jackets are a little hit and miss in terms of the sizing. I recently bought the Typhoon rain jacket and returned the Large for a Medium because the large was too big. I have mountain hardware shirts that are M and L and pants that are also M and large. Moral of the story is read the reviews before you buy. They are typically right on the money and will help you get the right size.

how do i fix small holes?? they are about pencil tip in size, jacket got trampled at the bar. sucks im losing feathers
thanks

Duct Tape is the classic mountaineer's fix for little holes. You can also pick up Nylon gear tape, or Gore-Tex patch kits. They will all do the job nicely.

Or for something that looks kinda high tech, a dab of seam grip works, dries clear and is like a little window into the jacket...

Nitrous down jacket

Iam 6'0 210 ordered xl very tight under arms. The foreign company that is making this jacket need better ways to measure for a xl fit. I have a xl mountain hardwear jacket from 2 years ago and it fits great. Nice slim fit if only under the arms would have a little more room

5 5

light as a feather yet very warm

The Nitrous down Jacket is comparative to the Patagonia down Sweater, the Marmot Zeus, and the North Face Diez. But it looks better and has a very nice athletic fit. It's a light down sweater with 800-fill and is surprisingly warm. It’s great for layering on snowy, wet cold days and a good stand alone on warmer dry days. If you want durable, toasty and bulk, get the Sub Z. If you want water & wind resistant get a shell. I’m 5’10” 165 with athletic build and could have worn the medium for snug fit but got the large so I could get several layers under it.

Nice Jacket... but... TIGHT fit under arms.

I really like the Nitrous... but be *warned*... its cut fits very "snug" under the arms... more so than any other Hardwear jacket I've owned.
I'm 6'3", 215 and have longer than average arms.
I bought the XL. The arm length is generous... and all other aspects of the jacket are great.
Before you rip off the tags... definitely wear this jacket for 20 minutes when you get it to assure the underarm fit is OK.

An awesome and versatile jacket!

This jacket is truly an example in stylish versatility. In selecting this item, I did a thorough comparison of the competition (Patagonia, The North Face & Marmot) and this was far and away the best option. It's great for layering and as a standalone piece in not-too-chilly climates (>30 degrees).

Though it's not the garment's fault per se, the sleeves are slightly too short for my longer than average arms. For my slim nature, 5'10", 34" sleeves, 30" waist, 140 lbs, it fits very well and looks good in the process.

Material-wise, it's top notch, with a robust down filling and a hearty outer fabric. Though not exactly waterproof or downproof, it does provide great wind protection and warmth as you need it.

All in all, I need to shave my arms down by 1" and then this jacket would a five star, knock your socks off, piece of outerwear. Enjoy!

Light & warm!

I am pleasantly surprised at the warmth of this jacket given its light weight. It's great.

Great Jacket

I have really enjoyed this jacket. It is extremely lightweight yet very warm. Overall i am very satisfied with this product as I am with 99% of my other MH products. A couple things to consider. I'm 5'7" with a muscular build. I had to go with the large as the medium was just too tight. The sleeves could have been better engineered in my opinion. There are down jackets out there that have some kind of elastic or fitted material to keep the sleeves from hanging down past your hands. This jacket doesn't have that. In addition, while it isn't a big deal, MH should have considered adding zippers to ALL the pockets rather than just the top one. The flap is fine, but I would prefer to have a zipper to keep my stuff secure.

I'm 6'5 and 175 lbs. What size would you recommend? I also have long arms, (I have an XL Epic Shell) to go over this jacket in really cold conditions.

Stick to xl if you have long arms....

Good jacket, but better options out there.

This is an average down jacket. It's an almost exact comparison to the Patagonia Down Sweater, the Marmot Zeus, and the North Face Diez. It's a light down sweater with 800-fill and a lightweight ripstop outer. It's fairly wind-resistant, though I didn't think it was down proof. The Diez seems like a better jacket for the same price, but the patagonia is the best of all four as it is windproof with the same warmth as the others. The Zeus is by far the best deal, and it's marmot quality, so you'd be set. Three stars because it's an average down jacket at a very premium price.

Another close comparison is the Western Mountaineering Flash Jacket
The WM is a little lighter (9 oz vs 12 oz), but I have been consistently impressed with WM down over practically everybody else. The WM is higher priced ($260 vs $220), but it also has a hood. As a side benefit the WM is manufactured in the US (San Jose, CA).
I agree that the Zeus is a great bargain, and although very good the MH & Patagonia are better. My wife has the MH & I have the WM. The WM has better construction, but in all honesty, I don't see someone really being disappointed with the performance of any of those listed by James or myself.

recomendations for washing this jacket?
its got a slightly greasy aroma to it from being worn a lot and slept in a couple times, the type of smell gear gets when skied in a bunch. want to get rid of the smell but I cant just toss in the dryer on fluff with a dryer sheet so I guess I have to wash it.
i'm afraid as I dont want to ruin it, i like it too much
thanks for help.

A garment like this can be washed in warm water by hand or in a FRONT LOAD washer. Nikwax makes a down wash which is available here. I'd recommend washing it separately. Be super careful with the wet jacket, cradle it when you move it.

You can line dry or, preferably, use a dryer on low. Put a few clean tennis balls in the dryer with the jacket to help restore the loft

Good as new!

Forrest. There are washing instructions on the inside of the jacket. But, to save you some time they look something like this:

Machine wash cold gentle, do not bleach, tumble dry low and remove promptly, do not iron, do not use fabric softener, do not dry clean.

I hope this helps! Keeping it clean will help it to last longer. By no means will you ruin it. Cheers!

I'm 6'2" and 170# and I wear a medium in this jacket.

Xia4179080 Yes Medium would be perfect. I am 5'8 152 and medium is perfect. Small you will be miserable and will be unable to add any base layers if you wanted.
