Mountain Hardwear Nilas Jacket -

The Nilas Jacket is the centerpiece of the Speed Alpinism collection developed by Mountain Hardwear in collaboration with Swiss climber Ueli Steck. Designed for fast-moving, arms-up alpine climbing in cold temperatures, the Nilas packs expedition-parka-like warmth into a garment that weighs just 631 grams; some users report that they are comfortable using it as their warmest layer on Denali, where the average parka weighs well over a kilo. The Nilas is stuffed with 850-fill Q.Shield water-repellent down, so you can safely stay warm even if your hydration bladder leaks all over it in your pack. The torso is fully-baffled, while the arms are sewn through for less weight and bulk.

In keeping with Ueli Steck's personal style, the Nilas is pretty minimalist in some respects; it doesn't have a chest pocket, and there is only one pull cord for the hem adjustment. The stealthily hidden hood adjustment cords require you to unzip the jacket slightly to make certain adjustments, but on the other hand, the cords won't whip around in high winds. The Nilas has a one-way zipper, so belayers should take note. The two stretch mesh pockets on the inside are generously sized for water bottles and other necessities, and have been universally praised for their utility.

The cuffs at the end of the sleeve are one of the Nilas' best points. Made of Mountain Hardwear's "Butter Jersey" material, you can slip your thumb and fingers through them to create a perfect seal with gloves, or put your whole hand through the big hole when you don't feel like dealing with thumb loops.

All in all, we would venture to say that the Nilas is the finest down jacket ever to grace the racks of Outdoor Gear Exchange. Pair it up with the Nilas down bib pants and you've got Himalayan-style protection at a much lower total weight. Mount Washington via Huntington Ravine in January? A winter ascent of Katahdin via the Cathedral trail? Ice climbing in the Dacks when it's cold as all get out? The Nilas is the jacket to have for all of these.

Mountain Hardwear Nilas Jacket Reviews:


I just received this piece and I am pretty stoked. The Colors.. Not so much. Anything with bright Pumpkin orange just isn't my thing. Maybe it is like that feeling people get from being around a pasty white Ginger with freckles? Creepy.. I know. I got the Shark with the Pumpkin liner. I guess it is like a Ginger with a tan if that is possible? I was almost thinking about going for a Blue one from last year but the fact it doesn't have the Q Shield down was the real deal breaker. Plus, Backcountry's 30% off deal was too good to pass up.
The Jacket is puffier than I expected, yet because of the internal baffles it doesn't have the overly exaggerated Michelin man bands or compartments you get used to seeing on many down coats. I tried it on side by side with my MHW Sub Zero from a few years ago. Man that Sub Zero is short and much more bulky. The Nilas is perfect in the length and just has a better fit over all. I couldn't really tell which is warmer, though I would grab the Nilas because of the weight and being more compact. I am stoked about using it as a belay jacket this winter and using it on Rainier throughout the year.
The best way to describe the warmth of the jacket... Lets see... Ok.. Do you remember the 'Empire Strikes Back'? Where Han Solo slices open the Tonton and he stuffs Luke Skywalker in it.. Yeah, but in this case the Tonton is orange.. So a Ginger Tonton. That would actually make more sense of why Han Solo was so grossed out by the whole experience. But seriously... Gingers are just like normal people.. LOL.. Ok I tried. I just couldn't say that without laughing.
*For the PC induced people out there.* I have a few Ginger friends and this is the normal banter all of our friends flip them.

I've had this for about a year now. For the weight, I don't know that there's a warmer jacket out there. This is one of the real flagships of the MH line, I like it as much as my WM Vapor.
I've tested it in the Tetons in winter, wearing only an Arc'Teryx Phase AR half-zip underneath, at night in 15 degrees with 25 mph winds. Even when I wasn't moving or being active, I was as toasty as could be. The Airshield shell fabric performs as advertised; blocks the wind, is durable, though it's a smidge crinkley. I also wore the Nilas in the Sierras on a shoulder season trip, and though the conditions were warmer, it proved its breathability and versatility.
Two years or so ago, MH made some claims that they were going to put their name back on the map with some real advancements/innovations in their technical gear. I feel this jacket is a testament to their statements. It stuffs nice and small, the detail on the fleece cuffs and hood are first rate, and unless you're headed to Everest or Denali, this jacket should keep you warm . If I have a hesitation, it's the oft-heard complaint about MH zippers (usually with their bags). I say, treat 'em with a little respect, and you'll be fine.
I'm 6'2", 200 pounds, a Large fits me perfectly. And I love the Shark color.

Just returned from an unseasonably cold April in AK! I used the jacket on two glacier camping trips where we had temps of -10 to -20 almost every night. I used to use the big and bulky, but warm and toasty classic Absolute Zero Down Parka and thought this jacket might not be a warm enough replacement, but it is. It's the perfect around camp super down layer. It's really packable too and won't take up half of your pack should you choose to carry it with you for the day. It's not as durable feeling as the Absolute Zero, but we'll see how it holds up. I'm a big fan of lightening up wherever you can if you're not sacrificing certain functions. There doesn't seem to be any sacrifice here.
Thanks Ueli!

I bought the Niles Jacket in the early fall of 2013 and only recently had the opportunity to wear it. The local temps dropped to 12 degrees F with winds approaching 35 mph. I Zipped up the jacket to just under my nose, tightened the hood and walked outside. I discovered that the wind and colder temps had zero affect on me. I was warm and toasty. The Niles Jacket is the best investment I ever made. If I was scaling MT. Everest, I would take my Absolute Zero Down, but short of that, I'll wear the Niles.
