  • Q & A

What size do I need for an Alaskan winter Maybe Denali base camp
I am 6 foot 2 inches and a 47 inch chest and at 66 YO I am starting to feel the cold To wear over base layers + ThermalPro fleece and a Patagonia DAS in XL as my mid-layers
DAS is a few seasons old now and about as warm as a new Nanopuff

Your probably looking for an XXL which gives you a chest of 48-52in and would give you ample room for the base layers. it does say the jacket fits slightly large, but the XL runs from 44-46in and may be a good fit without baselayers, but tight with baselayers

Runs +1 size large

I'm a solid XXL in most jackets/shirts etc....I have numerous down jackets from MH that barely fit in the XXL size. This has extra room in an XL, I could almost go down to a L. Undoubtedly they assume that you'll probably be wearing 3 or 4 other layers under it, which you likely would be summiting an 8000M peak. If you don't, size down at least a size.

Hands down the best expedition parka on the market. I will be going overboard and taking this with me to Aconcagua in January. The detail and quality of this jacket is bar none. The sleeve cuffs are great to keep any drafts out of any area between jacket and mittens. You can tell MHW designed this with the mindset of not taking off your mittens/ gloves. The hem cords and zippers are very mitten friendly. It does come up a nice stuff sack, but I strongly recommend getting something like the Sea-to-Summit eVent dry compression to stuff it down even further, and to keep it from getting wet at all. I have a picture shown of the stuff sack it comes with. I would say it does fit a little bit large. I am typically a L in just about everything for a top, and I am right in-between a M and a L. If you like to have a looser fit or have longer than average arms, then stay true to size, but I can fit into the M just fine.



Feel free to reach directly out to me for any questions about this jacket or your next big expedition trek!

Best High Altitude Jacket

Fantastic!

  • Fit: Runs large
  • Size Bought: Large

Let me preface by saying that I haven't tested this in cold weather yet since I just received it- mid October in New England. But it is well made, with lots of features and there is an abundance of down! I spoke to Greg B, a Backcountry sales guru and we decided to go with the Large. Glad I did!
I'm 6'4 and 200 lbs and usually go with XL in most brands- even Mountain Hardwear. But this is very roomy in the Large.
I just tried it on with: a fleece zip pullover, a Mountain Hardwear Ghost Whisperer micro down jacket, (excellent) and a Fjallraven down vest underneath!! Plenty of room to zip up and not too tight! So definately size DOWN one size from your normal.
I doubt I'd ever need all those layers, but nice to know I could do so.
Also, the fabric is a great weight-not too thin, but just right for this type of parka. The sleeve cuff treatment is very well done. No Velcro tabs, just integrated jersey cuffs with thumb holes. Fluffy down everywhere-no empty spots. And the State Orange color is awesome.
Congrats to Mountain Hardwear on this "tour de force" effort.
Also thanks to Greg B who "knows his stuff". A real Pro.
Pricey, but worth it, particularly if you get it on sale which I did.

UPDATE
Have used this in 0 degrees. Nice and warm.
Also, the other night outside in my 0 degree down bag.
Windchill at -25. Wore fleece pullover, a down micro jacket and this parka which we call BIG Orange!
TOASTY!
If you have need for a brute like this , buy it!

Warm and well made.

    I ordered this extra warm parka for upcoming winter here in Vermont. I like wearing only a tee layer underneath. So this parka has the features to deliver. Looks good. I ordered a L and like loose fitting, which this is on my 5'10" 200 pound frame.

    I want to know the appropriate size ? Gender: Male Height: 5'8 " Weight: 160 lbs Thank you

    Super warm

    Perfect for cold and windy conditions. Usually I get cold under the arms and around neck but so far I have not had that problem with this jacket! (Used 20 days pluss)

    Super warm

    What's the compressed size of this? I'm comparing it to the Feathered Friends rock and ice parka, which compresses to 7.5" x 15", or 17L for medium

    Truthfully., I don't have any physical dimensions for you, but I can say that when I have it in the stuff sack, it completely fills out the sleeping back compartment of my Osprey Atmos 65 backpack. And at 539 gram of 800 fill power down, you'll be plenty warm for sure!

    What would be a woman's equivalent? I am going on a photo expedition in Iceland in February… Lots of standing around and I need to keep warm. Thanks!

    I was stationed in Iceland for a year. You don't need this much warmth. Iceland's climate is moderated by the gulf stream which flows around it. Do the research on the temperatures year round. If you were going to Greenland, then you would need a coat like this.

    I was stationed in Iceland for two years and no it doesn't get super cold there like northern Alaska, but the wind chill get's crazy. I would have loved a jacket like this when I was there.

    Not sure what size you will need though. You might contact the seller.

    This actually a nice jacket for Iceland when you do photo tours. I own and operate a expedition company in Iceland and we specialize in photo tours. In the interior of Iceland we often se -10 og -20 Celsius an add on the wind chill when you are out hunting the auroras for hours this is the jacket to go for... I have one and use it often!

    I love this parka so much I have it in Shark and State Orange.

    It leaves plenty of room for layering underneath it, which makes sense because in and of itself it won't be warm enough for the environments where it is envisioned the wearer will be. However, if you're simply someplace like MN or in the NorthEast where extremely cold weather sets in, this on its own will probably suffice. I have no doubt that even in the coldest environments where I've lived (-14 F in DC with windchill in the Winter of 1995) this with only a tee shirt or thin baselayer will keep you extremely warm.

    Zipper alpine pockets are cavernous along with the handwarmer pockets too.

    Unless you plan on wearing this on its own, I would suggest against sizing down but go with your true size.

    If you don't mind, can I please ask you what is your Chest size to fit Large size?

    Is this jacket helmet compatible?

    Yes. I have an older one from 2011/2012 and am able to wear both my Petzl Meteor and CAMP Space 2.0 helmets with it comfortably.

    Overview of HM Absolute Zero Down Parka

    Does this parka come with a stuff/compression sack? If not, what size sack would you suggest?

    I just recieved my Absolute Zero parka and yes it does come when a sack. It's a bit bigger than it needs to be though, so you'll probably want to find something smaller to save room in your pack. (It's about the size of my 15 degree sleeping bag with the included sack, and it can definitely be compressed more.)

    I have the nitrous 800 fill down jacket and the exposure shell. Together they weigh around 47 oz. Would they worn together be as warm as this absolute zero jacket which has 800 fill down and weighs 49 oz? The absolute zero has an insulated hood whereas the nitrous and exposure combination hood is not insulated. Is this the only difference?

    This jacket is way warmer than the Nitrous. The shell weight has no insulating properties. A jacket like this would go over your nitrous and exposure shell. I used a down sweater, micro puff, then a shell, and had this jacket for the extreme cold.

    Thanks!

    This jacket is actually owned by Bill whose review is actually located below, it's a size XL, I'm roughly 5'5" 130lbs, and this thing comes down over my knees when I'm standing straight. It's about 4 inches longer than my arms as well. BIG JACKET. FEEL LIKE A PUFF BALL.

    Jacket to Sleeping Bag Combo

    I think you might need to size up a little bit. Looks a little small.

    I agree with Mr. Glaubman on this front.

    That jacket looks too tight to possibly perform basic functions.

    Size up at least 3x. :)

    That selfie was taken at 10,000 ft while hunkered down on Denali. The storm raged for 3 days before we could move, we needed to wear everything we had to stay warm. After that we continued on to ski off the summit and bag a few more ski lines in the area. I appreciate your input but, I believe Denali has some of the most extreme conditions out there and is at a fairly high altitude a mere 20,320'. Sorry you felt this post was ridiculous, haters gonna hate....

    I took this monster to Aconcagua and Denali - both trips this year - and it performed amazingly well. I wear a large, and am 6'2" and 195 (in reasonable shape). On Denali summit day I wore 2 base layers, a soft shell, and an Atom SV under this and was toasty warm despite very cold temps and high winds. In other words, plenty of room to layer. I suggest a compression stuff sack for this garment - it is puffy. BTW, I tried an XL and it was too big all around.I am frankly surprised that there are not more reviews of this parka here.

    Thankfully we didnt have to wear it to much but when we did it worked. You definitely lose some dexterity when wearing this jacket its HUGE and PUFFY and keeps you warm in almost any kind of cold. I am sure there are places where this would not work and I probably wont visit them. I am 5'8" about 200lbs bought and XL to make sure it would fit over my other jackets and it was perfect.
