The Mountain Hardwear Sub Zero SL Hooded Jacket wraps you in 650-fill down to keep you warm in the coldest possible conditions. Mountain Hardwear made the Sub Zero jacket with Conduit SL laminate that prevents moisture from sneaking in and breathes when you warm up. The detachable hood allows you to customize the jacket to the weather, and the fleece-lined collar and hand pockets add extra comfort when the wind starts to howl.

fantastic sub zero jacket

    High performance jacket that keeps you cozy and warm in the coldest conditions. Just used it at camp and as my back-up jacket for climbing and skiing at higher altitudes in Bolivia, and in some fierce winds, and was well protected. Detachable hood and other great features like lined pockets and collar. I am 5'8 and athletic build- Medium was the perfect size. WARM!

    This one won!

      I tried out eight down parkas and this is the one I finally chose. The fit is good for me (size Large--I'm 5'5', about 150 lbs.) and the style wraps me in cozy warmth. The Icefall is a gorgeous color but I went with black just for practicality. Can't wait for next winter to enjoy it fully.

      Yes its great

        Like everybody else, I love this jacket. Very weatherproof, a light rain runs right off it. Fantastic hood. Unlike most women's coats, it actually fits real women; long enough in the arms to actually move them, big enough to wear layers under it (yes it does run a little big), long enough to keep your butt warm, enough room in the arms and shoulders. And it really fits like a women's coat, not a man's. Also unlike most women's coats, it is actually warm! Very warm! No sewn thru seams or cold spots. Yes it's not the lightest thing out there, but it's pretty light and for the price it's pretty high performance. Wait for a sale and you will have a great value in an all purpose winter garment.

        Very Warm jacket...Perfect

          I bought this jacket for a photography trip to Yellowstone in January. This was a great coat. I got a break in the weather so my coldest day was -7 with a pretty fierce wind but this coat just laughed at it. I have no doubt that it will handle minus 20 and further. I loved the interior pockets for keeping camera batteries warm next to my body. The hood comes quite forward and can block your side view but absolutely great for when the wind is really blowing...It really scrunches quite small for packing and can be stuffed into included bag...although that was a bit of a wrestling match. All in all...loved the coat even though it is not the least bit sexy or flashy as you can see from the picture.

          Very Warm jacket...Perfect

          Warm as a Goose!

            As a girl who is known for always being cold, I can tell you that this jacket can keep anybody warm. I recently purchased this jacket for myself to keep warm during Canada's long cold winters, and let me tell you; I fell in love. When you think of a down jacket one might worry that it would make you look puffy. Yet I found that all this jacket does is make you look smart. It fits true to size and has nice oversized pockets with zippers. It also has a nice big hood for those extra hold days. This is the perfect jacket for those girls who just can't seem to kick their chill. This little goose will warm you up and block out wind and snow in no time.

            Order a size smaller

              I ordered this jacket in a medium based on the sizing chart and it is HUGE. It hung off my shoulders and I had a good 6-8 inches of room in the chest. I exchanged it for a small and the small fits me perfectly.

              I'm going to follow-up on this review after having this jacket for almost a year. The hood is what makes this jacket so unbelievably warm. By insulating your head and neck and sealing out the cold, your whole body can stay warm. I also have to comment on the laminate finish on the fabric. While it does shed water, it also sheds....engine paint!! My boyfriend shook a can of florescent orange engine paint that ended up having a hole in the can. The splatter got all over this jacket. I was sick until we started working to remove the paint. With some mineral spirits, all the paint is gone and you'd never know it even happened. I couldn't believe it.

              Sleddin' in a SubZero

              I wear my SubZero puffy all the time! This is one of my favorite jackets and I love how it cuts out the windchill while snowmobiling, keeps me dry while storm skiing and looks good when going out. This jacket is very puffy and warm, but with the pit zips you can air out and avoid overheating.

              Sleddin' in a SubZero


                I have had my SubZero SL for 6 years now and this one for my girlfriend. She would often layer up, with 2 or three jackets sweaters ect.. Now it is just one and we are out the door. Warm, comfortable, and she wears it with everything so I would say it is fashionable as well.

                Love it.

                  I love this coat. My boyfriend purchased the men's version last winter and I frequently wore it and wanted my own. The hood is key. It really keeps the wind out. I live in Minnesota and this past week has been well below zero and I have stayed warm thanks to this coat. My only wish is that it was a tad bit longer.

                  Mtn Hardware coat

                    This is the second mtn hardware coat I have purchased because they are so well made. This is a great jacket if you are looking for warmth and a hood. It may be a little warm to ski in on most days. The size runs a little big; I wear a medium and M is just a little roomy. The colors are pretty, they appear satin.

                    Super warm but heavy in the pack

                      I love this jacket. It's crazy warm and a small gives me room for a few layers underneath (even a down sweater) which makes it even warmer. I wore it this am when it was 19F with only a thin sweater underneath and I was just fine.

                      However, it's HEAVY. If you're a weight weenie, keep looking. I bought this to take on summit bids, but when you're counting every gram that goes in your pack, this jacket can bog you down. But when I'm not worried about weight, this is my go-to jacket. Otherwise I use a lighter down jacket paired with a down sweater under a shell -- these two weigh less and take up less room than my SL. Also, I'm always a little concerned by items marked "water resistant" so I prefer to have a gore-tex shell as my top layer for climbs (this is too puffy for that).

                      YMMV. I do love it though.

                      So very warm!!!

                        This is the warmest jacket I've ever owned for sure!! I've had it now for about a year and it looks just as new as the day I bought it. It's kept me warm in around-zero degree temp's with snow a-falling. (usually I have to just wear a thin tee-shirt underneath so I don't sweat!) The pockets are great as well- fleece lined, soft, and toasty! Cinch-cords at the bottom and with the hood are great as well (and the hood's removable so that's nice too.) I'll admit I do feel like the michelan man while wearing it- it's very puffy!!- I'm 5'10", 130lb and it's a tad big, I prob should've gotten the small- but it's still awesome!!!

                        Hardwear down jacket

                          I was told by a customer service rep that this was the WARMEST jacket they had. They were right! The quality is excellent and even the collar inside the hood is thick down. It is a beautiful jacket, appropriate for our frozen Wisconsin winters. The only problem was the color made me look like a total corpse and for the cost of the item I had to love it. I like colorful outer wear and already have a boring navy coat. I returned it but only out of my own sense of style. If you want the warmest coat-EVER, they this one is for you!

                          Very Warm but too problematic

                            I loved this jacket (so warm) until it ripped after 3 months. I don't know how or why because I basically walk to and from work in it and that's it. I called Mountain Hardwear about it and they said they'd fix it for $90 plus S&H. I was appalled by this but then the guy on the phone was a total jerk. I called to complain about the jerk and the assistant manager and the manager basically called me a liar! Nobody from customer service was helpful in any way. I will never buy Mountain Hardwear again. My boyfriend has a similar Patagonia jacket and he loves it (and if there's a problem they fix it or replace it free)! Stay away from Mountain Hardwear unless you are willing to be belittled by the "customer service".

                            Sick jacket

                              Lucked out and got it for $59 on clearance...couldn't pass it up...great jacket, I'm 5'6" 135 and the small fit but a little tight w/ layers, got the Med and its perfect. They must have added length to the torso and sleeves b/c this jkt has the best length I've seen for both. Great hood coverage even with a helmet and reverse zip for belays! Too bad it doesn't come in 800 fill and w/o extra linings to keep it lighter. Still a good buy if you can get it around $100 or less.

                              MJO. I would say it is shiny-er than it is matte. The jackets are made with a 100% Rip-Stop Nylon Shell which kicks off a bit of shine for sure but it is fairly normal for this type of fabric on this type of jacket. Hope this helps!

                              I am very long waisted, I am wondering if this jacket will be long enough to keep the "junk in my trunk" warm? If not, what hooded jacket might you recommend?

                              I'm 5'5" and 180lbs. I received this jacket as a gift in a Large and I feel like I'm swimming in it. The sleeves and the chest feel huge but the bottom is just right for my hips. But- from what i read this jacket is supposed to sit at the waist instead. I need some help. Should i return this?

                              I am a plus-size female and very interested in the Mountain Hardwear Sub Zero SL Down Parka, but the womens sizes only go up to 16, and I normally wear around a 20/24. I prefer my coats to fit large, so I would wear my coats at least a 3x or 4x. I am looking at the mans sizes to see if that would fit me, but I'm afraid the sleeves would be too long. Can you tell me if other women have purchased the mens coat and complained about the sizing? Thank you for your time. I desperately need a heavy-duty winter parka, but have a hard time finding PLUS SIZE for ladies.

                              Best Answer

                              K.M. I would go ahead and purchase a men's size. I am not exactly clear on how the sizes correlate but you will probably find the closest fit this way. Also, it is possible depending on your height that the sleeves could be a little long. There is only one way to find out!

                              Does this jacket come with a stuff sack for it? I'm looking for a down jacket with a removable hood for camping above 9,000 ft. I always get cold in the tent in the evenings, so I want it something warm, long enough (so when I'm sitting my lower back doesn't get cold), and is convenient for backpacking (weight doesn't matter much to me).

                              Best Answer

                              well, this jacket definitely is warm if that's what you're looking for. not sure if it would be good for skiing. i usually ski in just a non-insulated waterproof jacket with a couple good layers underneath--even in miserably cold skiing i'm fine with that after a warm up run. as for sizing, i'm 5'2" 125 lbs and i got the medium. i got it rather than a small because i wanted to be able to put a thick fleece and a base layer underneath. she could probably get away with a small. no worries either way though--backcountry has a hassle free return policy if she ends up wanting a different size. hope this helps!

                              Linda. Due to variation in individual metabolism and countless variables we don't put temperature ratings on jackets. With that said, if you read down through the reviews you will fined that folks have been happy with the jacket in pretty cold temperatures. It is baffled like a sleeping bag (no cold spots), has a removable hood, and fleece lined pockets to mention just a few features that make it suitable for sub freezing temps. Enjoy!

                              Colleen. Check out the Woman's Downhill Parka. It is essentially the same jacket as above but with added ski features and added length. If the jacket is for you... with your measurements I would consider a small. Hope this helps!

                              Is this completely windproof? How water resistant is it? Does it shed snow better than rain? How durable is this, is it prone to rip if snagged or caught. My wife's biggest pet peeve, does the velcro get caught or stick to the fabric (she's had that problem w/ other jackets). The last question will be the deal breaker for her.

                              Best Answer

                              jsung. The jacket is completely windproof and highly weather resistant. It is made utilizing Conduit SL fabric which is waterproof. But, due to the construction of the jacket (no tape) we call it highly weather resistant. So, with that in mind... it does shed snow better than rain. Also consider, if it is raining... it may be to warm for a down coat. The jacket is made with a combo of rip-stop nylon and more durable taslan and is no more or less prone to ripping or snagging than any other down coat out there. The velcro does not, in my experience, get caught or stick to the fabric. Hope this info helps!

                              Best Answer

                              Linda. It is very hard to say which jacket will be 'warmer' as every person has a different metabolism. I would imagine that the down fill in each jacket is similar in amount therefore making the warmth gained from the insulation similar. The TNF jacket weighs 545g and the Sub Zero SL weighs 745g so it could be said that the Sub Zero has more down insulation but I don't know that for sure. The difference in weight more than likely comes from the fact that the Sub Zero SL is made utilizing the Conduit Laminate from Hardwear which is our waterproof and breathable laminate. The Sub Zero SL is not a waterproof jacket due to construction (not taped) but it will provide superior weather protection to snow and light rain when compared to the TNF jacket. Also, the Sub Zero SL is baffled like a sleeping bag (no cold spots)... not sure about the TNF jacket. Hope this info helps!

                              amy. I am not sure of your measurments but the best way to see if the xs will fit is to go to our sizing chart located on this product page on our website: (hint: cut and paste into your browser), click on the sizing chart PDF and go from there.

                              Hey there! I'm about 5'11" and 140lbs, and I was wondering what size you think I might want to get in this jacket- I'm normally a small in the torso (and size 4-6 in pants) but I'm worried about sleeve length, as that is a problem I often find with Mountain Hardware/most outdoor gear! Thanks so much!

                              Best Answer

                              Tall and skinny... well, in order to fit your arms you may have to go with a jacket that is a little larger in the body. So, I would say @ 5'11" you would probably be the most comfortable in a large! A medium might work as well but I think you would run into the sleeve length issue. Good luck!
