When you need to hunker down from brutal weather high in the mountains, turn to the Mountain Hardwear Men's Nilas Down Jacket for lofty warmth you can count on. The precedent-setting Q.Shield Down 850-fill insulation is infused with a permanent water-resistant treatment that allows the down to stay warm and lofty in wet and humid conditions. The active fit is specifically designed to be used with tools, harnesses, packs, and the like.

  • A lightweight down jacket for high-altitude climbs
  • AirShield Elite 15D ripstop blocks the wind
  • Q.Shield down retains maximum loft even when wet
  • Baffled construction eliminates cold spots
  • Insulated hood keeps a low profile while active
  • Hand pockets stash snacks or cold fingers
  • Buttery soft wrist gaskets lock in the heat

Swing and a miss for me

  • Familiarity: I returned this product before using it
  • Fit: Runs large
  • Size Bought: Xl

Materials are great. The colors are nicer in person. This could have been the ultimate belay and winter coat. The sizing in xl was ridiculous around the belly.good in arms and shoulders. Worst part... the arms are not gusseted. You raise your arms up the jacket goes with you. I’m not sure why this has not been mentioned in a review yet. Maybe you guys don’t care. But for a jacket meant for climbing or any jacket for that matter, the hem should stay put when you raise you arms and not expose your RIB cage when up. Fix that and the overall fit and you have a hall of famer.

Terrible zippers

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: M

I bought this for my husband for Christmas. We took it out of the box and immediately could not work the zipper. This level jacket should really have next level zippers and it was not the case. We are returning and will be purchasing a different jacket. Super bummed out because we typically love Mountain Hardware products.

Zippers, zippers, zippers...

  • Familiarity: I returned this product before using it

On this jacket belong to a $120 jacket. At the price of this jacket, I expect quality zippers rather than ones I have to struggle with, esp worse with gloves, to operate them. Adios!

I have had a NIlas Jacket for over 6 years now, I have never had an issue with the zippers and appreciate the fact that they do not self adjust/lose purchase and open up. The craftsmanship ensures that a breeze doesn't creep in along the seems and the closure is tight to prevent wind/moisture from settling in and creating a snag in very cold temps. I would guess a defect which warrants your return, but would strongly urge consideration as weight/warmth/compression/function and craftsmanship define a jacket that has been used/abused for years.

Puffy warmth

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: Medium

Didn't put this through the ringer by any means. Just borrowed it to keep my girlfriend warm on her first backpacking trip ever. Let's just say she was glad I brought it.

Puffy warmth

First backpacking trip, and in snow! Wow

Great Jacket

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

This jacket does a little bit of everything. It is extremely warm for the weight and is much more weather resistant than most down jackets without any weight penalty. The collection on features is very nice. I love the huge drop in pockets on the inside, the are great for keeping gloves or other small items or to keep a waterbottle from freezing. The cuffs wrap your wrists really comfortable and just feel right. Overall, this is an awesome choice for a belay or a camp jacket with the added benefit of low weight.

My warmest jacket

    This jacket is TOASTY! I use this on the coldest days of the year. It feels like you're wrapped in the most comfortable down comforter ever. I've worn this in 20 degree weather with just a t-shirt underneath and didn't feel even a hint of cold. I loved the liners in the wrist for extra warmth.


    • Size Bought: Large

    After 2 winters, I finally decided to go with this jacket for my snowshoe camping trips. I wanted an end all cold layer for overnights in the Mahoosics in Maine and this coat does it. I feel toasty at 10° with winds howling. I'm short and stocky at 5'6 190, so the length covers my bottom nicely. I do have a little room for my active mid layer under if the temps get below zero. I'm confident I can be out at higher elevations with no problem.
    Also, just wanted to say the service at Backcountry is top notch. I was counting on a this coat in 2 days and this piece and another came exactly on time. Thanks Backcounrty for making my trip stress and cold free!

    What's not to love!?!

    I really can only say good things about this jacket. I upgraded from a decade old Mountain Hardwear Puffy to this and am absolutely blown away! This thing packs tons of warmth into a lightweight coat and doesn't make you look like the michelin man. It is extremely comfortable and warm and has lots of great pockets.

    A great alpine piece or belay parka.

    Bomb diggity uber warm!

    • Familiarity: I've used it once or twice and have initial impressions

    I gave this to a friend for a trip climbing and it was a great belay layer! It is the kind of jacket that you put on if you were active and now are stopping and need some great warmth. It would also be a great alpine jacket, and the best feature is the cuffs at the wrist which allow your gloves to go over them easily, and keep out any wind or snow! He used a size medium, which was a great fit and he is 6'2" and 165lbs.

    Great Jacket for High Alpine

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: L

    This is my go to jacket for winter expeditions. It is lightweight and compacts nicely. The AirShield nylon gives me confidence it isn’t going to shred into pieces and the Q.Shield allows me to not get too nervous if it does get moist. I’ve used this in UT, CO, and MT on high elevation climbs in Winter. I love this jacket for just about anything except for major expedition likes Denali or the Himalayas, I would want my Absolute Zero there.

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

    • Fit: True to size

    Are you looking for a super warm, lightweight jacket? This is the one for you. This jacket is perfect for warm walks in the chilly mornings or when you are taking the kiddos out to see the lights. Instant warmth and comfort. It will make you feel like the Michellin man, but you won't be freezing like your friend with his ultralight slim down puffy.


    Super warm, super comfy!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs large

    Don't plan on getting cold in this jacket! This 850 fill down is so soft and compressible, it's like you're wearing your favorite down comforter. I love this piece! I was able to test it out on a short hike near my house. The temperatures got into the 40's with some sleet/hail falling. The AirShield Elite nylon ripstop material did a good job of deflecting the water to some extent. But this does not have a waterproof membrane, so a heavy rain would penetrate the piece. The jacket still has Q shield to protect from moisture wetting out your down to quickly, so it will still maintain insulative properties if you get it a bit soggy. But overall, I wouldn't plan on using this in the rain or other super moist environments. This jacket is meant for being in the snow, and other dryer, colder conditions. It would be great for a winter expedition, and packs down so well for such a lofty jacket! I thought it fit a bit on the larger end of standard size mediums, but that works perfectly for where I am on the sizing spectrum.

    Great Jacket for Colorado Winters

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium

    Bought this jacket to use for winter 14ers and snow camping here in Colorado. So far, I have found that this jacket is extremely warm, handles wind well, and does great in snow. I plan to use this jacket for a few 6,000 m peaks in Bolivia in June and am confident it will do great as a summit parka. Highly recommend it!


      The jacket is very warm, -15c in a tshirt and i am very confortable while standing still. the jacket fit loose as a Large but no air pocket around me, it's a perfect fit to wear as is or to put over my shell. I'm 5'8" 180lbs. It is breathable, windproof, cuffs are perfect, everything of this jacket is perfect to me. Highly recommend.

      Setting the record straight

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

      I think this jacket gets a bad rap on other sites. I think the newer version fixes any of the misconceptions out there.

      So -

      It's light! My medium weighs 688g

      It's extremely puffy - Throwing on a backpack or hopping in a vehicle feels like the jacket is inflatable as the air squeezes out - the 850 fill is noticeable

      It's warm - I can wear just a t-shirt under at -15°C and still be comfortable

      It's box baffle construction all around, arms too - there's some confusion that this is only true in the torso.

      The hood pulls are accessible from outside - they're hiding under their own flap, and can be tricky to get to with thick gloves, but it can be done

      There are two hem pulls - one on either side

      There's a two way zipper - and it only catches on the draft tube sometimes!

      Fit: I'm 6'2" 170 and am happy with a medium. I can wear a MH monkeyman fleece under it comfortably, but it's not at all baggy. Sleeves are just long enough for my lanky arms, but the body and length fit well. Even though it's hip length - even for me - it tends to ride up a bit if the hip cinches are pulled too tight. A large would be too big for me unless I planned on piling on layer after layer, and I've got a warmer jacket for that.

      Hood fits well, easily adjusted, lots of visibility, and the tall collar sits just below my nose. nice for keeping the wind out.

      I live in the Arctic with daily temps around -25°C and use this as my everyday coat (office clothes underneath) I don't notice the wind or the cold creeping in anywhere. The Nilas has been really toasty so far, but my MH Absolute Zero is too warm.

      I got my Nilas for $350. I don't know if I'd spend $500 on it, but I'm very happy with it for the price I paid. It's functional and has a nice clean look so you don't feel like you're summiting Vinson Massif when you walk into the office.

      Great review! May I ask where in the Arctic you live? Want to compare temperatures. Thanks!

      How to Measure:
      All measurements correspond to equivalent body measurements, not the dimensions of the garment. For best results, take measurements over your underwear.
      Measure under your arms, around the fullest part of your chest.
      Measure from the center of your back to your wrist with arms held out.
      Measure around your natural waistline, keeping the tape a bit loose.
      Measure around the fullest part of your body at the top of your legs.
      Using pants that fit well, measure the crotch seam to the bottom of the leg.
