    Warm but NOT durable

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs large
    • Size Bought: Medium
    • Height: 5'10"
    • Weight: 185lbs

    First off, these pants are extremely warm and comfortable. Wore them in single digit temps on a windy day. No problems with staying warm. But the material is not very durable. I carried an extra Gopro battery in one of the front pockets, and in a span of 4 hours, it had worn a hole in the fabric, from the inside out. Why have pockets if you can't carry anything in them, out of fear of damaging the fabric. Knees and seat fabric held up great tho. Haven't contacted Backcountry about possiibly returning these. I would hope they would at least give me credit to buy something else. To sum up my review, buy these if you want warmth, just don't use the pockets.

    Saved my ...

      Those pants saved my lower parts! Used them in Canada in temperatures between -20 and -30C and stayed warm! Easy to put on and off with the full length zippers. But they also work great under hard shell pants as insulating layer.

      • Size Bought: MED
      • Height: 5'11"
      • Weight: 162lbs

      I bought the pants to climb Aconcagua. The pants did their job keeping me warm, but during my climb the pants got holes in each pant leg. I don't see these pants holding up, since after one climb they have holes with the down coming out already. The bottom of the pants don't have tear resistant material on the legs like the top part of the pant. At the ended of the day they did get me to the summit, but wouldn't €buy them again. I would spend the money and go with Feather Friends or something better.



      What size did you order? I have similar dimensions and am trying to decide if I should go with a medium or large. I would probably be wearing a thick polypropylene baselayer leggings underneath them so I would need them to not be too tight fitting. Thanks!

      Warm, cozy and comfortable!

      • Size Bought: Large
      • Height: 5'8"
      • Weight: 175lbs

      These pants arrived fast, washed well with Woolite and dried on low temp with a tennis ball in the dryer to fluff them up. The fit is true to size. There are zippers that run from the waist down the legs and two velcro tabs at the waist, one pair inside and one pair outside for a perfect fit.

      Cold weather has no chance

      • Height: 5'10"

      I bought these a while back and only get to wear them when it gets below 30 degrees in New England, because if you wear them and it is not cold enough, you will be really hot.

      I typically wear them for snow blowing, shoveling, winter camping around the camp, and anytime I need to be outside in the cold for an extended time. I only wear a pair on underwear underneath, nothing else, they are that warm. Paired with a pair of good socks and high Gortex boots you are good to go.

      My only negative thoughts, not really complaints, the front pockets zipper the wrong way, and kind of hard to get things in and out of. Also, in deep snow there is no inner lining so the snow can go right into your boot/socks, although you can tighten the bottom with the velcro strap which helps a little but doesn't prevent deep snow from entering.

      Overall, a super warm pair of fancy, fluffy pants to wear outside in cold weather and never be cold.

      Perfect for frigid conditions

      • Familiarity: I gave it as a gift but have feedback to share

      I bought these as a birthday gift for my cousin. He wanted them to wear primarily on COLD ski days under his bibs. They're also great for lounging around the yurt/tent. The full side zip and zip fly make for convenience and the reinforced back and knees give piece of mind. Fairly light and packable.

      Perfect expedition pants

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size

      Bought these to fit over all other layers on bitter cold days- ie, -10 F, and these are perfect. Around camp, I throw these on over a base layer and it's like wearing a sleeping bag on my legs. At night I stuff them in my sleeping bag or use them as a pillow. The knees and butt are super tough and I'm confident these will stand up to a lot of abuse. I had my eyes on these for years, they are pricy but even so I waited far too long to purchase these pants. Now, I'd never be caught in the winter without them!

      • Fit: True to size

      MH lead the way in synthetic climbing pants and these suckers are hard to get hold off and sell out in med and large as soon as they hit the shelves and now i know why. They are awesome, they fit well ( i am 34 inch and wear med), keep you toasty warm, are good to climb in and best of all have reinforced backside and knees. These have become the standard now on Denali.

      Full side zip

      The zip starts at the top and works its way down.. So no bending over and struggling to get the zip started at your ankles. A velcro tab at the waist (inside and out), and one on the outside at the cuff keeps the zip where it needs to be.

      Kind of a poor pic for it, but you can see the different materials on the knee and seat.

      Full side zip

      Better than your favorite sweats..

      Thanks to and Mountain Hardwear for choosing me to review the Compressors for the benefit of the community.

      My need for these pants is a bit unconventional, but they have performed flawlessly and have worked out better than any system I’ve used in the past. I do a lot of cold water diving- water temps are hovering between 36F and 38F- and these have become my under-drysuit-layer. In the past I’ve worn layers of fleece which left plenty to be desired. Now I head to our gear locker with my bottom half clad in gym shorts and these Compressor pants.

      I’m 6’1” with 36 waist and 32 inseam. I usually have issues in the thigh and butt area: tight in the thighs and big in the butt, but the large fit with no problem. They’re super roomy (not baggy) and have a little extra length. There’s plenty of room if I wanted to layer under the pants, but at the same time they fit nicely inside a pair of shell bibs or my drysuit.

      The Compressors are reinforced in all the right places. Cuffs, Knees, Butt, and adjustment tabs on the waist all are a tougher; not ski edge or crampon proof, but they’re definitely more abrasion resistant. The waist is super adjustable with tabs on each hip and a drawstring in the front. One big perk, unlike your favorite sweats, these babies have a zip fly! On the zip note, the full length zips along the side are stout enough to be functional and jam-free, but don’t cramp style by digging into legs.

      The synthetic fill (Thermal Q. Elite, they call it) is ideal for the dampness associated with diving- keep insulating even when damp/wet. The puff to the pants is preemo: not too much, not too thin. The outer layer is slippery enough to allow the puff to smooth itself out, thus avoiding poorly placed bunching.

      Bottom line: High Quality Pants. The folks at MH really put a serious level of thought into the design of these which pays off by way of form, function, and a stout helping of heat each time they’re donned.

      Mountain Hardwear Compressor Pant - Men's

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size

      I usually wear a size 34-35: pants and measure 38" circumference around my waist, I ordered an XL in these pants as I wear pants underneath and they are a perfect fit, The only issue is that there should be some way to tighten up at the waist other than the hokey string but they are good pants just the same.

      I hunt with these pants

      • Fit: True to size

      Now that you read the title, I am not busting brush with these pants, they would never hold up to that. I love that the zip runs the entire side, makes getting them on in a treestand easy. I typically pack them in to ovid overheating then put them on once I start to chill.

      When it snows and the family goes out, I always end up letting the wife wear these as over pants, shes considerably smaller than I am which shows a range of fit.

      Excellent Pant!

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I do love these compressor pants from Mt. Hardwear. They are very warm and comfortable. They are pretty true to size, though do run slightly long which I don't mind. I weigh 175 and am 6' tall and got a Medium. M/M. They fit great, allow good movement with layering without being too baggy. I've worn them with my jeans underneath at -17F this winter with 30mph winds and wind chills -40F and was warm. They have velcro synching straps at the bottom so you can secure them snuggly around your boots etc. Intelligent design. I've walked in deep powder with no snow getting into my boots. I also love that they zip all the way, so I can put them on even if I already have my Sorrels on! My only gripe is the reinforced knee/butt area material. The fabric loves to pick up everything from lint to dog hair etc. and it's hard to brush off. If they would use a slick nylon material like ballistic nylon, the pant itself wouldn't do that and be better reinforced. Other than that I love them!

      For short crotch sniffers..

        Great pant for the taller Cro Magnon shaped man and even good for the ever so stout Neanderthal and less evolved shorter mono browed dudes out there.. I am shaped like a brick. I think I have been called "Built like a brick shithouse" by more than a few. Imagine trying to find a pant to fit Fred Flintstone... Yeah, it kinda sucks. But these actually fit well and I can get them over climbing pants. The mediums still give me puffy butt but not nearly as bad as the large did. There is quite a big size difference between the two in the waist, butt and legs.

        Just an FYI.. The new ones don't come with a stuff sack either, maybe that was last years thing and the description hasn't changed?

        Puffy Pants!

        • Familiarity: I've put it through the wringer
        • Fit: True to size

        Warm and very comfortable. I even did some climbing in them and they breathe fairly well when you unzip the side zips. If you want something warm that is functional around camp and beyond this is the way to go, love these! Wouldnt wear these as an outer shell climbing your crampons or even the ice will shred the material, its not meant to be durable or worn as a stand alone piece unless your just sitting in camp.

        Not for me.

        • Familiarity: I returned this product before using it

        I returned this product because the drawstring was essentially useless in tightening therefore I couldn't get the pants to keep from falling down. Also, one of the reasons I bought these was for walking the dog on cold Minnesota nights. The material was so thin and cheap that the dog could have easily ripped through when she jumped on me, as she gets excited for her walks. Overall I'm disappointed with the design and the quality of materials.

        Great pants

        • Familiarity: I've used it several times

        These are a great pant. Nice for sitting around camp at night as well as great to sleep in. Wore them with just boxers under them in sub 30 degree weather and was perfectly comfortable. The more durable material in the seat and knees is really nice as well.

        Great Pants

          I plan to use them for winter outdoor activities. My primary reason was to use them for flying during winter and now I see several uses of these pants.Best thing is you can put and take them off very easily(side zippers).They have adjustable waist velcro tabs. These pants look really cool and happy with purchase

          are the legs big enough to pull over ski boots?

          Hey Chris, They might be - the size small leg circumference is 18" according to MH and goes up 1/2" each size. Feel free to give a shout at 801.204.4547 or and I'd be happy to help! Cheers, Connor

          I love these pants. Can anyone recommend an equivalent product that comes in women's sizes? My GF needs something of this sort, but she's petite - I doubt a men's XS would cut it for her.

          Hey Brian I know your question is old but I thought I would answer anyway....I had the same issue looking for down pants for backpacking. Since I couldn't find a comparable women's pair I opted for a down skirt instead and grabbed Toad & Co Cloudcover Skirt. It hits at mid shin and is awesome. It packs super small and is really lightweight but warm. I don't think the original use was for backpacking but in the cool months it is now standard in my backpack and works great layered over my merino wool base layer. Hope that helps.

          The skirt idea from sgb is a good call.. my wife has both a puffy and softshell skirt from Skhoop.. The puffy skirt she wears often in the colder months, but would use it as an extra over-layer during dog walks in the coldest months in Fairbanks (-20 to -50 f). The key there is EXTRA over-layer. They have tons of different versions, and there are tons of different companies making similar products.

          I was going to recommend Patagonia's DAS pants. They have a women's version with (obviously) more lady-appropriate sizing!

          Good luck dude.

          I have big legs, and I'm worried about how these will fit. None of Mtn. Hardwear's hiking pants fit me. They either fit in the legs and are HUGE in the waist, or they fit in the waist but they're skin tight in the thighs.

          I'm 5'9" and about 190-195 lbs. I'm a former football player and weightlifter and am currently a road and mountain biker. All of these things lead to big legs! My waist size is about 34", and the ideal inseam is 30"-32".

          I measured the circumference of my upper's just under 25". I am a little chubby right now, so I'm sure I can cut 1"-1.5" off of this measurement by the time I will be wearing these January on Aconcagua.

          Any thoughts?

          Best Answer

          You and I are much the same specs - I am 5'9'' , 195#, 32 waist and 25 thigh. I have 3 pairs of MH pants with 32 waist and they all fit the thigh. This particular medium compression pant will take a 34 waist but the regular length will make it long for both of us. As for quad fit I can't say for sure but I am sure it will (I have the MH windstopper full zip pants and they fit fine) - if you can wait a couple of weeks I am going to buy them and I'll let you know for sure.


          I'm in your same boat. 6'1'' and a solid 220 if not 230. Depending on the brand, I usually wear a 36 waist, but have pants in 34 and 38 depending on the sizing/brand/whatever, and I’m a pretty standard 32 length. I have the same issue when buying pants, they fit me length ways, my waist is fine, but they’re super tight on my thighs. I just got the Compressor pant in large regular, and there is plenty of room all around. The waist is pretty adjustable and has a drawstring along with adjustable velcro tabs at the top and cuff. There is plenty of room in the crotch, thighs, knees, and butt to do anything from climbing to high kicks. I really like that the knees and butt, along with the Velcro tabs are all a beefier reinforced nylon. They're a good fitting and super comfy pant for a bigger dude. Hope this helps- and I’ll put up a more complete review after some more serious use than sitting on the couch and high kicks in the kitchen...

          So I got the Neoplume pants yesterday. I opted for those instead of the Compressors because they're lighter and less bulky even though, based on reviews I've read, they insulate just as well as the Compressor pants. I'm heading to climb Aconcagua in January and the Neoplumes were recommended by several guide's gear lists. The price was also better, which always helps! I haven't had a chance to test them yet, so can only comment on the sizing...which was my main concern.

          I ordered size large, and they fit my size 34 waist well. I can slide them on over my hardshell pants with ease, and they also fit well under my shells because they're not super lofty. My biggest concern with sizing was the volume of the thighs as I have large thighs. There was plenty of I said, with or without layers underneath the Neoplumes.

          The only thing that wasn't perfect, was the length. I wear a size 30-32 inseam (depending on the brand of the pants). I have to hike the Neoplume's up to my belly button for the length to be right. Which isn't necessarily a bad thing...if they'd stay there. But they seem to want to migrate back down to my waist. Once they migrate down to where they want to sit naturally, they're a little long in the legs, and the crotch is a little low which would be less than ideal if I was climbing while wearing these pants.

          To solve this problem, I plan on taking these pants to a seamstress here who works on outdoor gear and have a couple suspender loops attached to the front so I can attach them to the suspenders of my hardshell pants...that'll hold them up just fine if I'm climbing in them. If I'm not climbing in them, I don't mind pulling them up every now and then!

          Hope this info helps someone. I'll copy/paste this into the Neoplume page as well.
