First off, I'm 5'7", 145lb, 30" waist, and the small fits nicely. I usually wear medium jackets, but I wanted a down layering piece that fit a more tightly. It's trim, but there's still plenty of space to move. This jacket feels very lightweight, but it is insanely warm. I can sit in 35 degree weather not moving and I'll get hot. I can't imagine using this skiing unless it was sub-zero, but for non-aerobic activities when it's cold, this thing is great to have. It also packs down fairly small---maybe to the size of a larger-diameter Nalgene bottle.

that keeps you real warm. The decision between the Mountain Hardware Sub Zero Jacket and the similiar but higher priced North Face was difficult at first. However, after speaking to the representatives at Backcountry and my own research led me to the Sub Zero. I love this jacket. It keeps me toasty warm, is very light weight, extremely comfortable and was a much better value than the North Face. It is also less "bubbly" than the North Face which was a plus. The customer service as well as the price and shipping on this product gives Backcountry a 4 star rating. This is a great jacket that I would highly recommend to anyone.

So I purchased this jacket with high hopes that it would fulfill the trusted and true Mountain Hardwear standard and this jacket has set the precedent on how 650 fill down jackets should be made. Toasty warm, moderate weight, stout and durable craftsmanship. Wore only a cotton short sleeve t-shirt under this jacket in 20 degree, 20 mph winds for 5 hours and was completely comfortable with no cold spots observed. This jacket can take temperatures much lower if layered correctly. My estimate is -20 deg. at the very lowest. Mountain Hardwear makes quality clothes / jackets /
pants / tents / etc. to stand up to the toughest Mother Nature can afford us. This jacket is dur-a-ble as well. Tough sewn in panels protect the high wear spots from abrasive materials rubbing away at the fabric which if not there would shorten this jackets life considerably. I can see this being my go-to jacket in freezing temps and should last me 4 winter seasons at a minimum. Bombproof and coldproof. Great product MHW, thank you.

I bought this jacket in San Diego prepairing for travel to Afghanistan and untill I got hear I was using it for a pillow. Now that it's cold I use it every day and it fits the climate.I'm at 3500 ft in south west Afghanistan with USMC and i get a lot of compliments about jacket, mostly someone want's to buy it. It's the best buy i've made in a long time.

great jacket for a great price. wear it often for cold days on the hill with nothing but a t-shirt underneath. worn it for over two years and no signs of stress.

This coming Canadian winter will shy away from the power of the Sub Zero. I'm super excited about this jacket. I wore it the other night when it was hovering around the frost point, without anything underneath it...and was still toasty.

Only thing i'd say is the short torso may not appeal to some. It's just fine by me that's for sure. I look forward to belaying in cold weather with this jacket, as the shorter torso is the perfect length for not interfering with a harness!

I bought this after a back injury caused spasms which got worse when the winter weather hit. I bought this and the Dome Pignon beanie. I dont think I could have made a better choice!!! I would buy it again when and if this ones wears out. I love the cocobolo color option - not your average color!

Holy Moley this jacket is warm, at one point I broke out into a sweat. Wow. I absolutely love it.
I'm not sure how it fits on men, but for a women, it is Ideal. I'm 5'7" and weight in at a buck 25.

It's very light and compact, perfect for camp but also something you'd carry on the climb. This saved my bacon at 13,000' last fall when we took the wrong way down...

I was given this coat as a gift at work (outdoor work) and it has been a great way to stay warm in any weather. It has faced four Utah winters. Lots of -20 (colder with wind) weather this winter in the Uintah Basin of Utah and never once even mildly cold. The only cold thing about this coat is anything it doesn't cover (legs, heads, etc.).
It holds up to abrasion and dry snow as well.
I even got battery acid on the sleeve and it didn't melt too bad!

I am 6'4" and wear an XL in mountain hardwear gear but I couldn't find a size in this that fit well. I realize that it is supposed to be shorter so it does not stick out under your shell, or so you can wear a harness but it was just too short. Ended up getting the BC luft for $50 so the story ends well. If this jacket fits you, lucky you.

Really nice jacket.

Fit: I'm 175 lbs, 6'1" and the fit is perfect.

Warmth: It seems plenty warm but I wont really know till the winter. I recently spent a few nights at about 4000' so it was pretty chilly (40s) and this jacket kept me plenty warm with only a t-shirt on underneath. I was a bit sunburned and exhausted (thus unable to properly warm myself) and this jacket really made the difference between a lousy evening and a comfortable one.

Packability: It comes with a stuff sack - once packed into said sack its about as tall as a nalgene and about twice the diameter. With a compression sack im sure you could do better. It does not seem that the stuff sack is at all water shedding so that needs to be dealt with by the user.

Other stuff: The materials probably would shed light drizzle but would not likely hold up to a down pour. I know this jacket is not technically a down-sweater but I'm planning to use it as such and I think it will prove to be very versatile as both a standalone and a layer.

We are in Yellowstone N.P. where we drop to -20F to -30F pretty regularly in the winter. This jacket is great at beating the cold.

This is the best down jacket in its class, hands down! I swear by Mountain Hardwear products, they have never disappointed me. I recently wore this jacket during the arctic blast that hit Montana in early December 2008--temps were -35 wind chill. Out of curiosity I went for a little walk to test the jacket out under these extreme conditions. To my astonishment my upper body was unharmed by the cold. Tough jacket.

Jacket is extremely warm. I thought fit was ok. Takes a little adjusting to the "puffiness" of it. I feel like George C. in the Puffy Coat for all you Seinfeld fans. The down tends to leak out too which doesn't bother me, but my wife doesn't like all the white feathers on the seat in her cars' black interior.

I am 5'10" and 165lbs and ordered the L, because I wanted to be able to wear as an outer layer over other things. As others have noticed, it is slightly short in the torso, but not too much and it stays down if the waist cords are tightened on my hips. Nicely constructed with tougher material on high-wear areas; more polished than my old TNF Nuptuse down jacket. Good value for the money. I also have the MH SubZero Parka (longer, so no problems with shortness but a bit too much except when it gets to -40C) and the MH Phantom Down Jacket (more fragile, but lighter and perfect to stuff in a pack when hiking/skiing).

This is definitely the warmest jacket I've ever owned. I'm 5'8" and 165lbs. Bought a Med. and it fits great. I love the fleece pockets and the extra large one inside. The only down side is the outer material. It does have reinforced shoulders but I snagged a sleeve and already got a small hole in it. Any recommendations on patching the thin material? Still one of my favorite jackets for keeping warm in the Alps.

Body is way too short and the down loss makes you look like a molting bird!

I wear this jacket in any weather (I've worn it down to -20F) and been comfortable. Looking back, I should have gotten the hooded version, but I'm happy with this jacket.

Very comfortable, fits true to size, and has lots of pockets!

This jacket is so warm we live were it gets down to
-45 to -50 as long as I wear a sweatshirt underneath I still good to go. I would check the sizes though first I'm 6' 1'' and 145 pounds and got a large which is a good size for me.

Super jacket. Incredibly warm and it packs down really well in the provided stuff sack. I'm sure with a compression sack it could be squished down even more. It's definitely a great choice as a belay jacket and the ripstop nylon and burly arm patches are a nice addition to ward off pesky ice screws & ice tools that seem to like munch holes down jackets. The only drawback (and it's minor one) about his jacket is the lack of a hood. Overall, a really great jacket and priced very fairly for the quality and workmanship.

I'm on my third sub-zero...absolutely love the jacket. It's great for those really cold days.

This is a VERY warm jacket with good stitching and zippers. Know that this is a climber's design, so it's cut a bit short at the waist for all you fashion folks out there. As for the puffy look others are writing about, if it's 10 degrees out, do you care about how you look? This is the warmest outdoor jacket I've owned. A few feathers pop out now and then, but I've noticed that about every down outdoor product I've ever owned. The feathers should be all gone in about a hundred years or so. Excellent product from an excellent company.

This is a nice jacket for the price. It was 5 degrees F this morning and I was warm as could be. I'm very happy with all my MH gear.

The best 650 fill light weight jacket on the market. I am 6' and it is a good fit. Would like it about 2 in longer in the trunk. It is a great car or travel coat though.

I'm 6'3" and 190 lbs. I ordered a large. It seems to be a little short in the sleeves and overall length. Also, there is a good bit of room in the chest and stomach of the jacket; almost to much. Seems like there is less down in the lower back of the jacket. I don't know if it was manufactured that way or if the down has just escaped over time. However the jacket is extremely warm. I wore it on a camping trip with temperatures in the teens and wind gust of 20 mph. I stayed warm the entire time. Great jacket, but I have to give it 3 stars for the fit. If it was about an inch or two longer it would be perfect.

I have now owned this jacket for about 4 years and have been very happy with it. Aside from being a very warm jacket, its construction is high quality and there is good attention to detail with its features. I am particular pleased with the fleece lined pockets and collar, as well as the elastic bottom draw cord that are located inside the pockets (so you don't have to take your hands out). It also packs down to a small size for easy packing. As per other reviews, the length may be a tad short especially if it rides up, but keeping the draw cords tight will prevent this. In my opinion, this is a better alternative to the seemingly ubiquitous North Face Nuptse jacket

living in boston, this jacket arrived in time to keep me warm for the early winter and it is quite light and packable.

I'm 5'9", 155lbs and bought a medium. It is a little big in the chest and a bit short (but the drawstrings can keep the cold out). It's possible that if it was a little more form fitting it would be warmer, perhaps I should have bought a small. It seems rather durable- the fabric hasn't ripped even though it has been snagged on brush when moving through the woods. I was hoping it would be much warmer, but that's what the expensive jackets are for, right? The price is right as well. oh yeah- it's looks good too!

gOOD JACKET. VERY WARM. STOOD OUTSIDE WITH IT ALL DAY IN DECEMBER IN TENNNESSEE AT TRIPPLE CROWN BOULDER COMP (IT SNOWED A BIT BUT NOT MUCH). DIDNT WIN, DIDNT GET COLD. WORE BASE LAYER AND FLEEC BELOW IT. AND FITS GOOD, DOESNT MAKE YOU LOOK LIKE THE FAT KID AS DID A PREVIOUS DOWN JACKET I HAD.

I am 6 feet 210 pounds and 44 inch chest. Got an xl and it fits perfect. Today was 40 degrees in the city and i was sweating in it.

I bought the black one for my 14 year old son and now his dad wants one too. It is warm, comfortable without being huge and puffy! It's not as puffy as it looks in the picture. It really looks good and works for so many activities. He even wears it to the ski slopes. Plenty of room to layer too. Mountain hardware is always a great buy! I love their womens stuff too.

I've owned my Mountain Hardwear Sub 0 for over a year now. This jacket will keep you warm for sure. On extremely cold days I couple this jacket with my Mountain Hardwear Monkey Man fleece and I am as toasty as when I'm sitting by the fire. These jackets are not designed to be waterproof so just throw your Gore-Tex shell on over it and enjoy the outdoors worry free. The included stuff sack makes the jacket compress nicely, but add a compression sack and you can make this jacket fit in even the smallest of daypacks. Try doing that with your run-of-the-mill parka and liner. If you want quality and warmth go with MH, don't let the pricetag scare you and don't pay the same or more for another brand just because of the name. They make quality apparel for outdoor enthusiasts. I wear this "puffer" all the time, whether it be up in the mountains or around town. The only reason I didn't give this 5 stars is that the sizes didn't fit me exactly how I wanted. I bought a small for my 5'8'' 155lb frame and it is a little short in the torso but not too much. The sleeves on the medium were just too long for me. This coat will keep you warm!

I don't think I have ever loved an article of clothing as much as I love this coat. I am 6'7" and have an XL that fits great. The fleece lined pockets are a really nice touch. I went for a quick spin on my motorcycle the other day, air temp was 24 and I was toasty warm. Sooo good.

Awesome jacket, came in a timely fashion to my home in far north canada. We are average -30 here and have put the jacket to the test several occasions already and it performs...and it packs very small with little weight

I got this jacket for my Dad on his birthday and he says he loves it. It's very warm, the Cocobolo is a good brown color, the fleece-lined hand pockets are nice, and the shoulder and elbow fabrics are durable. He says he's sure he will be warm when he has to go out and feed the horses first thing in the morning!

I had been wanting a down jacket for a while before I got this. I went into the local store and tried it on and knew it was the one I wanted. Super comfy from the first time I tried it on.

I'm 6'2" and about 195 lbs and I bought a large. It's roomy enough that I can layer underneath it no problem, but not too big that I'm getting lost inside of it. It's just right.

Though I will say this, its been the rare occasion that I've had to layer with this coat. I bought it primarily for the Sundance Film Festival because those January nights in Park City can be pretty brutal. It has done a great job keeping me warm. Paired with a good beanie (Mtn Hardwear Dome Perignon) it was all I needed to be comfortable in <20 degree weather. Great Jacket.

I realize that no jacket is really the best ever. But if it's cold in Park City, I pull on this jacket. It's warm, it breathes, the ripstop nylon is super durable (had a run in with a stucco wall, jacket doesn't have a mark on it), and it keeps enough moisture off to stand outside and watch pretty much anything. The cut is generous without being michelin-esque. This jacket is cozy, comfortable, good looking and long wearing. I've had mine for 8 years and it still looks as good as the day I bought it. This is the best, cold weather, stand outside and watch a winter concert at the Canyons, jacket ever. It's a little too warm for heavy activity, but packs up tight so you can throw it in your pack as an emergency shell/insulator for winter camping/snowcaving/ski touring.

This jacket is awesome and totally warm with one glaring exception- it is wayy too short. I'm 5'10" 175lbs. and this coat barely makes it past my waist. If I sit down or bend over slightly my lower back becomes completely exposed. This is quite annoying. How did nobody else found this as a problem?? I'm not even tall...

This jacket is not only super warm, it's super comfortable. I got it last year and it was perfect for those winter camping trips where you can't muster a fire. Defiantly the warmest jacket I've ever used. And don't worry about wear and tear. It comes with tough shoulders and after a year of use it hasn't lost any feathers and still looks brand new

Backcountry. Fantastic service. PROMPT, RELIABLE, shame about the taxation sydtem on delivery. UPS are beyond namely they will not hand over the item you have already paid fpr unless you pay them up front. Theree's a balance here between ordering quality gear in the appropriate sizes not available in europe and being penalized by the charges having to be paid up front. Its such a shame!!
