Here's what others have to say...

I have both the Subzero SL Jacket and the Subzero SL Parka. Purchased the jacket for Mt. Washington and then later the parka for Rainier and Denali.

Now I have two down coats sitting around!

I plan to hold onto the parka as I will be using it on future trips. Any reason to also keep the jacket around? As far as I can tell, the parka is just a longer version of the jacket (and I like the side pockets much better!).

Responded on

Not particularly. You're right about that being the difference. The jacket is shorter to allow easy access to backpack hip belts and climbing harnesses. If ice climbing, cold weather camping, and other like activities aren't something you do, there's not really a reason to have both.

LOVE IT!!! Warm from 40 degrees to -20, this coat is like wearing a cloud of warmth. This is tractable and not too puffy and it even fits into a small little pouch it comes with. It's great for traveling and packing as a primary or secondary coat and when packed away, it takes up no more room than a 2-litre bottle of soda (but with much less weight). Literally like a sleeping bag and with plenty of pockets, this down coat is definitely something I would suggest to anybody. No Cons what-so-ever!

MH Sub Zero SL Parka in Canada

This is a great parka with very good material and offering great value for the price. I tested it recently in Regina, SK Canada where the mercury dropped last week to -34C (-48C with wind chill) and the jacket lived up to expectations with only one other layer of protection. On regular winter days, it provides more than enough protection even for extended times.

The only downside that I've seen is that the main zipper is hard to zip up and seems to be of poor quality. My suggestion to MH would be to improve the quality of the zipper to make this an unbeatable package.

Sub zero!

Sub zero SL parka working well at the top of Lincoln Falls, Mt. Lincoln, CO

Hi, wanted to go camping in Norway all...

Hi, wanted to go camping in Norway all year round. Temps can get as low as -40c. Was wondering if I could settle for this jacket or should I go for an absolute zero? Of course I want the absolute zero because it seems to be the best jacket on the planet, but of course its over double the price. I will also be buying an athletic cut softshell (arc'teryx venta sv)So could perhaps layer it under my sub zero sl parka. I would like to know I could camp in the dead of winter there and not die with that setup. Any advice would be welcome. I don't want to go overkill with the other jacket but seems like from all the pics of people wearing this thing on top of mountains at altitude this thing could do the job with layering.

I'm from aus as well so I know also that when I get back if I have the absolute zero then I may never use It again but also want to make it back.

Responded on

I have this jacket, and I love it. Its super warm, and I would think that the Absolute zero would be overkill. I've belayed long windy pitches in weather down to -15 F and was plenty warm. If it truly gets too cold while you are sitting around at camp, you could always just grab your sleeping bag. I think that this jacket would be a much more versatile choice for you. Hope that helps!

Responded on

Andreja, I would recomend if you are going to wear a shell over down you would be better served with an 800 fill down sweater, or if you want a hood, an 800 fill down Jacket. Much more compact and extremely wrm. I would also recomend a hard shell for your outer layer. Arc'teryx Sidewinder shell is world class, I wear mine year round for rain or snow. And since your most concerned about survival and getting the most for your money this would be a more practical purchase. For camping in winter be sure to consider a good set of hardshell bibs. I'm small and light and this type of setup works well even for me in subzero F temps.

Responded on

I am norwegian - done a lot of wintercamping/climbing. Get old fashion 100%woolen underwear!!!!!!! (icebreaker, devold or janus) forget about syntetic things. I have Mountain Hardware down jacket - fantastic! I only use it when I am sitting still or in and out of the car. To bulky to go for long skitrips with a backpack.

could anyone tell me the fill weight of...

could anyone tell me the fill weight of the sub zero SL parka and the sub zero parka?(not the 650 fill power)
Is it the same or not?

Responded on

kakuhenrich. The weight in grams of down in each jacket is as follows for a large jacket: Sub Zero Jacket = 261g and the Sub Zero SL Jacket = 321.5g. I hope this info helps!

I have been tasked with finding a jacket...

I have been tasked with finding a jacket for my husband who is planning a business trip to Moscow next month. UGHHHH! We hear it has been 30 below zero in February and living in Florida he DEFINITELY does not have anything that even comes close to accomodating those kind of temperatures. HELP!!! Don't want to spend a fortune for a 7 day business trip- but also don't want my husband coming home with frostbite! What would anybody suggest?

Responded on

Amy, this is a quality parka and is very, very warm. It should work perfect for the trip you are describing.

Best Answer Responded on

I agree with Mike, I have the Sub Zero SL Jacket (same thing, just a bit shorter) and I live in Alaska, where it gets a little chilly. This jacket is excellent, and will keep his torso very warm. I don't know what else you've planned, but I recommend a good base layer for his legs, warm boots, gloves and a beanie or something for the head as well, especially if he plans on being outdoors for much longer than 15 minutes or so at a time. That kind of cold can rip right through you, so either minimize your time outdoors, or gear up appropriately.

Also check for returned/lightly used gear for discounted prices. Backcountry is a seller there, and they're super fast shippers and great to work with.

Awesome belay jacket

This jacket is amazing. Its super warm , it packs down small yet fluffs back up quickly, and its get just enough waterproofing to make it so that you don't have to worry when the snow or even sleet starts to fall. I use this jacket for belay duty while ice climbing, and its awesome for after you've made camp for the night on a peak. I even use this to sleep in on alpine climbs so that I can afford to bring a lighter sleeping bag. The hood is also amazing almost beyond description. With all of that said, the only downside to this jacket is that the down has a tendency to migrate a bit. It tends to move to the top of the arms, or to the sides of the jacket if you are sitting down. Its not super bad though, and I've never gotten cold because of it. Overall, I give it 5/5 stars!

Thee Absolute Best Jacket for the money!!!

got the jacket a few weeks ago and haven't been happier....or, warmer.
I live in Toronto, Canada....and with this coat, I wish I lived on Everest!!
I pray for cold weather and laugh at people freezing in their "Non- Mountain Hardware" sub par windbreakers.......all my friends have commented on it and I don't wear anything but a t-shirt underneath when before, I would wear 3 layers plus my Columbia coat (which, I still love) but no where near the same league as the MH.
Last thing....I'm 5'10, 170lbs and I bought a medium and it fits perfect............I love this thing!!!

Really got to test out my sub zero this weekend at the Chicago Bear game against the New England Pats. If you saw the game on tv you say that it was absolutely miserable and cold out there. Not for me! I was so warm and comfortable. I cannot say enough about how warm this coat is. I did not even have to layer up like I normally do. My son and I looked like twins as he got his last year and talked me into this parka.
If I had to give a negative, the only thing I would like changed is the zipper. Make it a little more heavy duty. I have had some trouble getting it started at the end. Other than that it is wonderful.

Hi, I'm an italian boy. I am 1.78 m, 66 kg, chest 92 cm, sleeve 78 cm, waist 84 cm, Hip 100 cm, Inseam 75. Which size will fit me?

Best Answer Responded on

After running those numbers, you're very similar in build to me. I wear a medium Sub Zero, with lots of room to layer. You could comfortably wear either the medium if you like looser garments, or small, if you wanted a tighter fit.

New hood design for 2010

I just received my Jungle green parka and it’s a fantastic piece of gear. I read numerous complaints about the hood using snaps to attach to the parka and was a bit concerned. The latest design for 2010 is now using a zipper system instead of snaps. It makes the hood very secure and draft-free. Love it!
Sizing tip: I’m 6ft, 210 pound, 45 chest, 36 waist and the large is a great fit with plenty of room for extra layers.

Is this parka with conduit?and is it waterproof?

Responded on

kakuheinrich. The Sub Zero SL Hooded Jacket does utilize the Conduit SL laminate but it is not a waterproof jacket as we do not tape the seams or weld the baffles. We put the Conduit laminate in this jacket to make it extremely weather resistant but not waterproof. If it's raining, it is probably warm and you may be using a different jacket as you would be overheating in this one. If you are looking for the warmest and most waterproof down jacket that we make... check out the Absolute Zero Jacket. It utilizes 800-fill down, taped seams, and welded baffles. I hope this info helps!

The pictures on this site for the Mountain Hardwear Sub Zero SL Down Parka look a little outdated. I'm thinking about buying this jacket, but for $300 I want to make sure I'm buying the new 2010 version. I've seen newer photos of this jacket on various websites, but I'd like to buy from due to their excellent service. Does anyone know if their selling the new version of this jacket. Thanks.

Responded on

Dennis. They are selling the most current version. Cheers!

Alert to Fellow Geaheads:
The Mountain Hardwear Subzero SL Parka will serve you better than any parka that I have tested from Land's End, Eddie Bauer, LL Bean or any of the "commercially advertised brands." With winter a week or two away - the following info. is important as to why this is a great parka, and a better choice than others:
1) Baffled Construction - This prevents the cold spots and loss of body heat that lesser garments with sewn through seams unfortunately allow! The Subzero SL protects you from cold spots and loss of body heat - very important!
2) It is highly wind resistant - due to its Conduit SL Laminate Shell. Thus, you will be protected from biting winter winds!
3) It is nearly waterproof - due to its Conduit Laminate Shell.
4) It has 15 ounces of Down Fill - a significant amount of down, which will keep you warm!
5) It has an Awesome Down Filled Hood - that is also Face Protective. Since 65% of our body heat is lost through one's head- a great hood is imperative! The Subzero SL Parka delivers here also.

Responded on

Unless i got a lemon, there is two serious cold spots on the biceps area. One on each arm. No, nada, none down. Hood is very good with face comfort and protectiveness. You do not loose 65% of your body heat through an unexposed head. Newest research has suggested that heat loss is equal throughout body, with the exception of digits (fingers and toes). I am returning my MH and sticking with LL Bean and Columbia.

Responded on

Dear Ray, No Manfacturer can guarantee that every one of its parkas will be uniformly filled with Down.
I understand your frustration, but based on my experience I would have trusted the Mt. Hardwear Brand and the Subzero SL Parka, and just asked for a replacement. I would bet you that the replacement would have been absolutely to your liking.
I base this judgment on the fact that I own four Mt. Hardwear Subzero SL Parkas - and not one of them has any coldspots or lower down fill in the area of the biceps. For the future, you might want to give Mt. Hardwear a second try. They have great gear, and the Mt. Hardwear Subzero SL Parka has proven itself among many many satisfied consumers. Hope you are open to this suggestion.

OK for light duty

For standing/sitting around in urban areas or in base camp, this jacket is fine and seems like it will keep you warm. If you intend on going thru any brush (or rubbing up against objects with even dull points or portruding angles), forget it--the material is too thin and will puncture or tear. Sizing seems large-I'm 6'3" and 200 lbs. and an XL was way too big (though sleeve length was about right). Not sure how the L would fit--probably fine in the chest and sleeves too short. I returned it due to the flimsy material.
