Men's Nilas™ Jacket 4.8 5 24 24
The warmest and lightest jacket available! Since I bought this jacket I take it on every trip I go! It packs small, super lightweight, feels and looks really great! Couple time it was windy on the summits, but this jacket keeps the wind outside. The only thing that worries me is that they claim it has buffle construction not to have cold spots. It does, but only on the torso. On the arms you can find spots (along the sewing) where there is no down. I have never been cold in the arms, it's just my observation. Overall, this is superb jacket, a little pricey, but you will never regret! I am 5'11'', 180 lbs, size large is perfect for layering (a little too big on it's own). March 13, 2014
Warmest jacket I own, hands down! This jacket is by far the warmest jacket I have in the closet. I am 6-4' and average around 185lbs and it fits great. I usually have to wear an XL to get the length that I need and then they fit baggy. I purchased the Large in this jacket and it fits great in the length and is roomy enough to add a few layers underneath but not too big. Most of the time I find myself shedding layers because this thing is WARM. The quality is top notch and the two chest pockets inside work well for anything you can think of. The only thing that would make this jacket better is draw strings on both sides instead of just one, and a zippered outside chest pocket. However, that being said I would still buy this jacket again in a heart beat and highly recommend it for anyone looking for a toasty down jacket. March 3, 2014
Puffy warm goodness! I bought the Nilas from Mountain Hardware directly. Sight unseen purchases make me a little nervous especially when the other reviewers didn't really answer my question about cold weather performance. Living in Minnesota has been particularly brutal this year, but the Nilas has made being outside a non-issue. It has kept me nice and toasty especially with the hood. Wind stopping has been very important and this jacket does it proficiently. I'm 5'11" with long arms. The jacket's bottom edge falls nearly to my mid-thigh, and covers my rear. The arms were my biggest concern, but they are plenty long and the cuffs are fantastic! I wear this jacket for daily use which is probably a bit overkill. It's super light, but just a tad bulky for driving around in the car. It's not terribly bulky, just a bit puffy.... something I'm totally willing to compromise for the amazing warmth and wind stopping powers! I've been out in a wind-chill of -30 or so and the Nilas just laughs the temp and wind. I highly recommend this for those who spend any time out in the frigid cold. You'll love this jacket!

Coated down is the future! Last year I sold my Rab Neutrino endurance as the fit was too trim and just did not seem to trap enough heat. Waited for a coated down option and this was it, only a few out there. This really is the future of down and synthetic has not done it for me during cold New England ice days. The design is great, as are the materials, fit, loft, weight, inside pockets, hood, zipper, Etc. Have used this for over 10 days so far including some guiding and long belay days. Has been nice but not tested too cold yet. It packs small and is super light, needs a smaller stuff sack also. I have yet to have issues with the outer pockets and maybe three have changed? Would have liked a lower belay zipper but figured that Ueli doesn't belay anyone! Also, it pulls up nice as it's not too long. Material seems nice, durable, and wind proof, I am also using a windstopper sheet under, so who knows. I recommend, for the weight, it's awesome compared to others in the class. The orange rocks as it's darker than most too. Nice job. February 5, 2014
Not Alaska tough Had this jacket for about a year. Left pocket jammed immediately and tore. Feathers everywhere, zipped it closed and haven't used it since. Right pocket is still working, although the zippers on this coat are complete junk. The front zipper is fraying within the teeth and jamming up more and more. The fabric is not getting caught on the edges, the zippers are fraying from the inside of the teeth. I use this coat for 5/6 months everyday in the winter and it is not holding up. 3 rips in the jacket. One from a gun slung over the shoulder. Am I hard on jackets? Yes, but this coat cost a pretty penny and is not holding up like my last jackets. 8 years on those two. Like the other reviewer said, there are cold spots in the arms. Wind gets through, even with the material claim. Windstopper in my other coats did not. January 14, 2014
Warm and lightweight My Nilas jacket is quite warm but also lightweight. My arm length is about 36" and it fits very well for an XL. The thumbholes in the built-in sleeve material came in handy in 7 degree weather. Zippers are strong and quiet. And it compressed into its accompanying travel sack nicely for my flight home.

Hot Body, Cold Antecubitals (inner elbows) The good: - Truly maintains warmth (tested to -17) - Inside material seems softer than fleece - Down is dense, yet packs down easily Okay, but could be better: - Outside fabric isn't tough - The cut isn't stylish (but its function over form when it comes to life and death) - Glove gaiter isn't useful - Hand pockets have no down between interior pocket and the body (air shield material may be nice) The bad: - The down in the elbow baffins eventually accumulate away from the antecubitals (inner elbows) leaving only the air shield technology to keep out the cold (which stops working when the down isn't there as an insulator--you can definitely feel the cold) - The down is still coming out of the jacket (even after a few months of use) January 1, 2014
this jacket is the bomb diggity seriously warm,fits great, the hood actually works. the water bottle pockets are great the wrist cuffs work great with gloves for a perfect seal. stuffs into a super small 2Liter stuff sack (included) sweet! December 16, 2013
Nilas jacket I go out for walks a lot.I find you do not even realize you have it on.So light.I went out the other day here in NH the weather was cold about 5 degrees with wind chill about -15.I only had on a tee shirt under and was snug as a bug in a rug. December 16, 2013
Warmth without the weight This is a fantastic coat if you're looking for excellent warmth in a lightweight package. I recently received this coat, so I've yet to go winter camping with it. That being said, I did go for an hour long hike the other day. The hike itself was not very strenuous, so I did not build up much body heat. The temps got up to -11F with windchill at -25F. This coat kept me plenty comfortable, even though I only had on the Beta Power 1/2 Zip and a light T-shirt underneath. What makes this coat though, are the many finishing touches. The cuffs and ridiculously comfortable. They prevent any kind of updraft while getting rid of velcro (which in heavy, wet snow is ineffective in my mind). There is also a good draft tube just behind the zipper. Not only does this prevent heat loss or some bone chilling cold coming through the zip, but it is finished with a piece of nylon on top of the tube, to prevent you from snagging it when zipping up the coat. I believe another reviewer had mentioned how they dislike the hood, but I rather like it. It is cut out a bit on the side, which does expose your face a bit. However, if you're like me, you'd prefer to have the 180 degree visibility and just wear a balaclava if it does get really nasty out. Just very well thought out details on this coat. Couple words of caution however. This coat is a bit crinkly. With the 15 denier face fabric and the windproof membrane, this is bound to happen. I didn't notice it when I was hiking, but I know a buddy of mine didn't buy the coat in large part because of this. Also, it runs surprisingly large. I am 6'0", 180lbs, 42in chest and ended up in a small. I tend to wear my clothes a bit more snug than some, but even then I have plenty of room for a warm layering system (think LS shirt, 1/2 Zip plus a 320g shirt over top) without feeling like a stuffed turkey. Overall, this is a fantastic coat if you're looking for warmth in a lightweight package. I've seen nothing from the competitors that truly matches up with this coat. Now I'm looking forward to trying to go do some winter camping. December 8, 2013
Niles Jacket I first bought the Absolute Zero Down Parka and the Chillwave Parka, but when I bought the Niles Jacket, The other two coats pretty much stay in the closet. The Niles is light but very warm. I'm 5'10" and weigh 205 and the extra large fits just fine. The light weight is just a bonus, because I have the feeling that the jacket will stand up to some pretty low temps.If, I need more, I'll grab the Absolute down. Until then, I'll be wearing the Niles coat. Phil Jacobs Pana, Illinois November 11, 2013
Excellent Parka I purchased this jacket several weeks ago and have been very pleased with its performance. The fit is excellent, it is very warm, and blocks wind like a champ. The hood is adjustable and fits great even when I'm wearing a climbing helmet. My only complaint is that the down makes me itch. When you're wearing it over several layers of climbing gear no biggie, but when its just a base layer and the jacket, it gets a bit itchy. This is, however, an excellent jacket and I would never give it up. March 3, 2013
Warm Cozy and Lite 5'10" 165 lbs. This is the warmest jacket I've ever owned and my favorite of all. It's amazing how the body heat is trapped within the jacket. By this I mean, on a cold day pull down the zipper and sticky your hand inside the jacket. It feels as if your hand is in front of a heater. I am so lucky I live in Portland, Oregon and have access to the Mountain Hardwear employee store. If not, I would still pay $500 for this jacket. In addition, I love the 2 large pockets inside the jacket. Thank you Mountain Hardwear for the Nilas Jacket. February 4, 2013
Great Jacket Snowboarded in 10 degree F conditions. The Nilas was warm the entire time. I wore a t-shirt underneath and the cold didn't get to me at all while several others in the group had multiple jackets on. The Nilas held up really well. January 15, 2013
Blew my mind! I have the Nilas jacket in a size large, which is true to fit (5'11" / 190lbs). Even for full price, I have to say that this beast earns every bit of its reputation with respect to weight, warmth, compressibility, comfort, durability, usability, and style. I also own the Chillwave Parka, but the major differences that I noticed between the two were weight and compressibility. Compared to the Chillwave (which still holds a place in my gear lineup), the Nilas feels like you're wearing next to nothing but will keep you just as warm. I recently used it on Pico de Orizaba in Mexico at camp, on breaks during summit day, and when the wind picked up to 40 mph, dropping the wind-chill to somewhere around 0 F. Even so, I had to unzip it on numerous occasions b/c I was trapping more heat than I needed. I used the stuff sack that comes with the jacket and the Nilas fit into it easily. You could probably fit it into a much smaller one, but might risk over-compressing the fill if kept too long (not sure). Either way, it lofts quickly and fits into my pack with the stock stuff sack. Considering the durability of the material, it's extremely comfortable. The chin guard was smooth and never chaffed my face in the slightest. The "Butter Jersey" cuffs are not only comfortable even while using the thumb loop, but stay in place and block cold air from entering the sleeve without the loop and when gloves/mitts are off. Also, the jacket's outer shell is tough and held up to numerous brushes against coarse rock and ice without a hint of wear on the material. The draw chords and zippers both feel flimsy, hold up nicely to repeated punishment. The only drawback here (doesn't rank high enough to change my mind about the jacket) is that the waist draw chord is only on one side, thus it has the tendency to bunch up on that side. I don't notice that it affects the function of the jacket, but can look a little weird. Even so, you can still work the material around so it's somewhat dispersed and looks normal after adjusting it. I have little to add for the hood, as it worked great and was a non-factor. It was warm and fit perfect with and without a helmet. I have the "Shark" color scheme and I love it. Not only does the Nilas earn its keep in adverse conditions but also looks stylish doing it. I would recommend this beast to anyone who knows they're headed into the backcountry in adverse conditions or to anyone who lives where it gets downright cold (easily fashionable enough to wear around town). If you care about equipping yourself with only the best gear to cut no corners, this is the best bang for your buck! I would have included a picture on the route, but this trip was solo. Yet another reason I was glad to have the Nilas since I didn't have anyone else to rely on if I got into trouble and needed to keep warm. Sets the bar high! January 9, 2013
Warmth and versatility in a lightweight package. Great piece. Super lightweight, very warm, yet incredibly versatile. I've worn this in weather ranging from -5 and snowing to 36 and broken clouds, and all with minimal layering. Temperature regulation is amazing, even w/o the pit zips, and the jacket is so light that you don't feel any bulk at all. I can't really attest to the ability to shed water, but for quick light squalls, the jacket worked great with water and snow beading up and shedding quickly. It never felt stuffy or over-bearing.. just nicely insulating and warm. January 8, 2013
Perfect for the Arctic! I have been wearing this jacket for a couple of weeks now. Temps have stayed at 10 to 20 degrees below zero during the day and the jacket has performed wonderfully. This jacket is amazingly light and comfortable! The low profile hood does not flap in the wind when down and the chin guard keeps neck drafts at bay. When up, the hood conforms very nicely. I cannot wait to wear it cross country skiing... December 7, 2012
Got it for Chicago Weather (and much more) I live downtown Chicago and walk a mile to work everyday. I got this jacket for the Windy and Cold Winters. It is super light and comfortable and I like the color combo being an Oregon State grad. It stuffs into my bag easily too. I also am a big football fan so I am sure this will keep me nice and warm at those. Finally, when I make it back to the NW for winter steelheading, it will keep me warm and toasty on crisp cold winter days. July 10, 2012
Sweet, Sweet Nilas After 10 years I finally decided to upgrade my nearly destroyed, recently hood-less and finally mostly nylon Sub-zero Parka. My Nilas arrived just in time for me to take it to Kahiltna International Airport, where I used and abused it for a week. The Nilas was everything I wanted in a down jacket. It was plenty light enough to keep in the pack and fit perfectly over my jacket at belays. The hood fit comfortably over my helmet and the sleeves were plenty long enough. The shell repelled moisture perfectly and it even survived a few direct hits with falling ice. No tears, nicks or cuts, and I'm not the most careful with my gear. This is a perfect on route, alpine jacket. In camp though, I found myself often going for a chest pocket that wasn't there, and wishing for fleece lined pockets. Still, even without these nice-ities, this is the best puffy I've ever owned. May 6, 2012
Surprisingly Warm. Crazy Light. When I first got this jacket, I was skeptical that it would be warm enough for extreme conditions given that it is insanely light and not very bulky. I was pleasantly surprised! In fact, I'm guessing this jacket would put up a good fight next to an Absolute Zero. TESTING: I used this jacket on a cold & windy ascent of Mt. Shasta's Casaval Ridge in April 2012. It was pretty cold - I would guess sub zero with the wind chill. Winds were reported by NWS to be ~40mph, gusting to 80-85mph+ (which felt about right). I was wearing a Capilene 3 base layer and Mountain Hardware's Densa Hoody (which I also love). WHY I LOVE THIS JACKET: 1. It's super warm. You'll doubt this given that the jacket feels too light & thin to pack much warmth, but it does. I would throw this on during a rest break and at camp - and would immediately warm up. 2. It's crazy light. It's hard to describe, but it just feels like it's going to float away (in a good way). You hardly know it's there. 3. It's tiny. It packs up in the included stuff sack (which I didn't use on this trip) or can easily be stuffed into a backpack (which is what I did). 4. It lets you skimp on the sleeping bag. I opted for bringing my warm weather bag (Mountain Hardwear Phantom 32) even though temps were in the single digits. I ended up sleeping with the Nilas Jacket on and was perfectly toasty the whole time. 5. It has great pockets. The two interior pockets hold a Nalgine bottle - I threw a water bottle in one and some snacks in the other. On breaks, I would just pull out the jacket and have water and snacks that weren't frozen. 6. Butter cuffs rock. The soft cuffs (with a thumb hole) completely rock. They're very comfortable, feel great, and make it easy to throw a mitten or glove over the jacket sleeve if needed. CONSIDERATIONS: A few things to be mindful of: 1. Trouble getting hood over helmet. I was wearing the Nilas Jacket on top of a Capilene 3 base layer, the MH Densa Pullover, and my Arc'teryx Alpha LT hardshell (all of which have hoods). I tried various combinations of wearing / not wearing certain hoods but had some issues getting the Nilas hood over my helmet. It would fit over but not snugly - and kept blowing off no matter how I tried to cinch it. Could just be the combination of layers on my part. 2. I wish there were two hem adjustments vs. just one side. I agree with AARosie's review that it tends to bunch up on one side. It's not a big deal, but it's slightly annoying. LAST WORDS: I totally love it. And highly recommend it. I am curious how the Nilas compares side-by-side to the Absolute Zero - but I wouldn't be surprised if it holds its own very nicely. And, with much less bulk. May 5, 2012
So light, so warm! I bought this jacket as an alternative to my current winter jacket. At 22oz, it is far lighter than my 3-in-1 ski jacket and much warmer. In fact, it's probably overkill and a tad too warm for my purposes. I recently took this jacket for a few days of snowboarding in ~20oF weather and ~20 mph winds. Not bad conditions, but with just a thermal layer underneath, I never felt the wind or a tinge of coldness. It packs into a small stuff sack, included, which makes for easy packing, since it is quite puffy. The internal pockets are great, and though unzippered, seem to hold onto things quite well. They are large enough for large nalgene bottles, etc. Though technically not waterproof, I did not have any trouble with snow melting through the jacket. To further test that would require warmer weather, which this jacket would probably be too heavy for. For improvements, I do wish it had is a 2-way zipper in front. April 18, 2012
My new favorite jacket This jacket is my favorite. Not only does it weigh next to nothing, it is packed with features and is super warm. Don't even try and wear this if it is warmer than 32F. It doesn't feel bulky because it is so light. It is so light and warm, you forget it is cold outside. Comes with a great stuff sack and if you want, you could fit it into an even smaller compression sack -- small enough to take "just in case". This jacket fits great. I wear a large in everything and it fit just great; there is still room to layer underneath. Lots of great adjustments. The butter cuffs are properly named. They are so smooth and soft. My only suggestion would be to have someway to pull the excess cord at the waste line into the pocket like many other jackets so it doesn't hang down when tightened. Last bit of advice; make sure you get the arms long enough. If not, when you use the thumb holes ( I don't use them very often as it is usually on top of my other layers) it will pull a little funny. It is hard to explain but cuff isn't sewn into the end of the sleeve. It appears to be sewn into the first "joint" between the baffles and pulls funny at that point if the arms are long enough. I felt like mine fit perfect, besides when I'm using the thumb holes, so I stuck with the large. In summary, this is an incredibly warm, wind-proof jacket. The quality is superior. This jacket will not disappoint. March 22, 2012
Super warm for its weight This thing is incredibly warm. I understand it's built to be as light as possible, but personally I can think of a few improvements that would add just a tiny bit of weight: -Increasing the diameter of the pull cords (the cords are super thin, I'm a little concerned about them breaking with extended use) -Adding a second hem adjuster (there is only one on the right side, and the hem tends to bunch around it when pulled) Other notes: -I love the butter cuffs, they work great with our without using the thumb holes -The hood fits very well with or out without a helmet. It's also easy to adjust -I usually wear a medium size. I am 5'11" and about 180 lbs and the large seems like the right size for me. I haven't used it in seriously cold conditions yet. It will see some action on Shasta soon and in Switzerland this summer. Based on previous experience I would feel comfortable taking this to Denali as my warmest layer. Not so sure about the Himalaya - if you're like Ueli and doing speed runs up those things I'm sure it's fine but for the rest of that don't have super powers I'm not sure it would be warm enough. All in all a great jacket - light as heck and super warm. March 15, 2012
Hyper light, Super warm This jacket is unbelievably light, weighing in at about the same weight as a windbreaker, yet providing as much warmth as the heaviest winter parka. Crushes down to the size of a grapefruit for easy storage in your pack. My only qualm is that the shark color looks black on the website but is really a dark grey color. February 23, 2012
