K7 Down Jacket

When it comes to unprecedented warmth in harsh conditions, the Mountain Equipment Men's K7 Down Jacket is your key to success on alpine ascents or Arctic explorations in frigid temperatures. Mountain Equipment stuffed this jacket with some of the lightest, loftiest, and softest 800-fill down available, and the jacket's box wall baffle construction eliminates cold spots. The Drilite Loft shell is durable despite its lightweight appeal, and it's completely windproof and highly water-resistant to protect you against whatever weather you might climb in. The K7 also features a helmet-compatible hood with an elasticized lining which is designed to hug your head for a snug fit. Not to mention, you can cinch it tightly with a helmet on or not. Hook-and-loop cuffs prevent necessary warmth from escaping, and the hem has a dual-tether drawcord for better adjustability.

  • A windproof and warm jacket for harsh, alpine conditions
  • Drilite exterior is windproof and highly water-resistant
  • 800-fill down provides serious furnace-like fervor
  • Bevvy of pockets keep necessities close
  • Helmet-compatible hood, hem, and cuffs are adjustable

I bought this jacket last winter, looking for something I could throw on for deep winter walks by windy lakes, in temps or winds < 10F. I've worn it maybe 20 times and been pleased. I got out today for a long walk when the temp was 6, feeling like -12 with strong wind, wearing a light synthetic underneath, and I was very comfortable, here and there on the toasty side, appreciating that I could unzip a bit from the bottom to regulate.

I'm 6'0", 185lbs, slightly athletic build, wearing a large. I like the fit wearing just a tshirt underneath, but there's room for at least a couple layers, which I haven't yet needed.

Make no mistake, this is an athletic cut top end alpine jacket. This will not be a good choice to hang out in while walking around in the city. However, if you have a trim athletic build, and are looking for a super warm, minimalist alpine jacket to use in the mountains with a harness, this is a great choice. For belaying in 0F weather, it's amazing.

A short review regarding fit...

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: XL

I'm 5'10", 190 lbs, exactly 46" chest (measured bare skin), exactly 52" shoulder diameter (bare skin, around deltoids), 36" waist.

ME's size chart indicates my size would be either XL or XXL. Wearing a lightweight zip neck merino top (Minus 32 degrees) and R1 hoody, the XL fit in the body was close, but not close enough to compress the down filling. Armpit fit was very close and, if I'd had another layer on would've been too tight.

Fit across shoulders at deltoids compressed the down. Down was also compressed across tops of shoulders (trap muscles).

Down fill in baffles around wrists seemed thin and this was concerning. However, the sleeves were about 2" past my wrists. When I velcro'd the sleeves in place on my wrists, the extra sleeve length folded over on itself, which seemed it would mitigate the thin down in the wrist baffles.

Lack of rear hood volume adjustment was very disappointing. Even with the facial adjustment snugged down a lot, the hood didn't move with my head. Also, the facial shock cords don't surround the forehead. They're attached to the ends of the hood brim. When you pull the shock cords the hood brim gets lower and lower, and will restrict your vision somewhat.

Also, because the shock cords don't completely go around the forehead, the forehead fit is loose. IMO a strong wind will make the hood flop all over the place.

Due to shoulder (delts and traps) fit I returned the jacket. Never wore it outside so can't speak to warmth, which is primary purpose the jacket should serve. Because of it's excellent prior reviews I gave it 4 stars due only to hood fitment and thin down at wrist baffles.

Initial Impressions - Good, almost great

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: Small

Just got this and the quality and craftpersonship seem first rate. Backcountry fulfilled first rate as always.
First impressions - Its weight is light for its size, not heavy or bulky. Definitely a performance piece. Sleeves in size small run long, perhaps thats if one is reaching up a lot? The overall fit is good, though I'm not a big person -5'7" 140, its an athletic fit. For me, the fit around the armpits is close, someone bigger won't be layering very much as it'll be too tight there.

The napoleon pocket should be slightly larger as it barely fits my Samsung S8. The hip pockets are big so lots of room if one carries things there. The critique here is the zip openings are too big. IMO the zip openings need to be slightly smaller due to heat loss when hands are in pockets and also because the inside of the inside of the pockets isn't insulated. So effectively its only a nylon barrier into the inner core where the warmth is when the pockets are open, like when your hands are in them.
I was warm, not hot, walking my dog on a 32 degree very windy day that had the feeling of being a much colder day. The hood was great, covered well without being overly big, this is a super improvement over my old hoodless NF Nuptse this jacket is replacing.
What was interesting was when I walked up a slight hill and my body temp rose slightly, I began feeling how much better the insulation was. I could feel the jacket retaining the warmth. Began thinking maybe I should vent some, which was nice.
So I would give it 5 stars in my short test drive, but lose half of a star for
-imo- needed pocket tweaks on hips and napoleon pockets and sizing tight under armpits. Still, I'd easily recommended it in my limited initial test run.

Yup. I’m 5’7” 165 Pounds athletic build. I love this jacket, only I also find it very tight under the armpits in a medium. Tried the large as well and it’s still a bit snug at the arm holes with the rest of the jacket being a bit to big around my torso. I’ve heard the Expedition fits true to size and might be a better fit as far as the armpit thing. (My usual size is medium). Note: I do have broad shoulders and strong upper back and chest , but it’s nothing as big as gym rat or body builder type...just an athletic build. Fjallraven usually fits me to tight at arm holes as well. Arcteryx Firebee and SV Parka fit me perfect only their hoods are big for non helmet use and find myself staring into the side of the hood when I turn my head.
I’d order the ME Expedition immediately if it was still available in the cosmos navy colour...but it isn’t.

I don't know why everyone doesn't use stretch baffles. It's a big coat that actually moves with you, and I think the stretch baffles make it more thermally efficient. If you are in the market for a jacket like this, definitely order this one up. I found that I was swimming in other jackets or was stuffed in them. I don't want to give up freedom of movement. Also, this jacket is set up great for belaying . There's great attention to detail in terms of durability. The bottom baffle is all outer fabric so it's more durable and you can sit without snow melting and wicking up into the jacket. This is a great feature that will come into play many times in the lifetime of any jacket like this, and that other manufacturers don't even think about!

Nice N Toasty!

Burly construction, fits like a warm hug with EXL stretch baffling on the inside. Not overly bulky for how much cold this thing can fend off. Love that there is a baffle along the zipper to keep warm air from leaking out the zipper seam. Collar and hood provide amazing coverage and you can really hunker down.

Great so far

I have never owned this brand before, but so far I really love this coat. The construction is great. It is very warm, it isn't too bulky but is bulky enough to keep out the cold. The interior, including the hood is gathered by elastic so it really fits to my body. Love the zippers.

I've been through many parkas in my search for the perfect down jacket. Nothing is perfect in this world, but the white whale is the nearly perfect balance between performance, comfort, and the compromises imposed by the laws of physics. For down jackets, I can safely say the Mountain Equipment K7 jacket comes the closest.
I don't use this jacket for climbing. My primary use is periods of being mostly static in freezing temperatures in a camp setting.
With 300g of 800 fill power goose down, the K7 fits in a bracket just under the heavier 8000m expedition parkas. As I understand it, Mountain Equipment uses the European down rating method, which essentially means the fill power is approximately equivalent to 850fp using the U.S. measuring standard. I feel this amount of down plus the 800 (850) fill power is the sweet spot for high level warmth, mobility, weight and packability. This balance makes for an overall more wearable piece in a wide range of conditions than the heavier types. However, the K7 is still a jacket with a primary focus on existing comfortably in below freezing conditions.
One jacket I compared the K7 to is the Arcteryx Ceres SV. Looking over the specs, you will see that they are very similar other than the staggering difference in full price. Build quality is equal with box baffled construction in the body and arms, water resistant, fill, etc. Both allow you to lift your arms overhead without lifting the lower hem of the jacket. However, once you have them in person, the differences make the decision fairly easy for me. While the Ceres is a well built piece, it exhibits far less loft than the K7. This can possibly be attributed to the baffle design, and a higher amount of down in the K7. For some reason, every Ceres I have seen has nearly flat insulation in the front arm crooks. The arms of the K7 are much loftier and consistent. Another factor was the hood. The Ceres was designed with a cavernous hood that might be good for helmets but is poorly designed for going without one. The K7 hood is amazingly well balanced in this regard and has the best hood cut I have seen. It fits the unencumbered head very well, but has an elastic lining that makes room for a helmet. Long story short, the K7 is a very refined and dialed in piece.
I also much prefer the shell material of the K7. It has an internal coating for water resistance, but still maintains a great flexible feel. The beautiful minium color looks killer in person and has a mini ripstop pattern. The plain weave nylon shell of the Ceres is heavier and much more crinkly because it has a Gore windstopper membrane. This will provide greater water resistance, but makes the Ceres heavier overall, and is overkill for a down parka that will be used in mostly colder dry conditions.
The inner lining of the K7 is silky against the skin and very breathable.
Many users will be happy with the main zipper on the K7 jacket. Many jackets such as the Ceres SV and Rab's Neutrino Endurance have zippers that regularly catch on the inner draft flap. The K7 inner draft tube is actually a continuation of the baffles coming under the zipper rather than being a separate flap. The contact area behind the K7 zipper never seems to get caught and the zipper consistently zips up and down smoothly.
One relatively uncommon feature that I really like about the K7 is the EXL lining in the back. This lining features elastic stitching in the baffles to help pull the jacket closer to the body to retain more warmth, but stretches to accommodate more layering. Its a similar system to the elastic I mentioned in the hood.
Elastic cuffs with Velcro straps are a welcome rarity for this type of jacket.
If you haven't worn Mountain Equipment products before, you might find that they run a little on the small side depending on your layering preferences. I wear xl in most jackets and went up a size for the k7 and its perfect.

    Favorite Belay Parka Yet!

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

    I was recently turned onto Mountain Equipment by grabbing their Eclipse Hoody, big competition to the R1 from Patagonia. Gave their belay jacket a try as well and fell in love!

    Its the perfect blend of weight and durability. There are some lighter puffies out there but, this one fights off precipitation and scraping the environment better in my opinion.

    I can squeeze it into an XS Sea-To-Summit Ultra-Sil Compression Dry Sack which gets it down a bit smaller than the stuff stack it comes with.

    The real kicker on this jacket is how it utilizes elastic lining to make it fit perfect despite differences in layering. For me when I am wearing this without all my layers on like in a sleeping bag for instance it hugs my body making it more comfortable but, also warmer as there isnt dead space to heat up. Then when I put this over ALL my layers (base layer, 100 weight fleece, synthetic layer, hardshell) it can stretch a bit and fit fine over all of that. The inner layer is also very comfortable on your skin unlike many other jackets. So when I take it camping or on a recent yurt trip I can wear it comfortably just over my t-shirt while working around the camp.

    Big deep pockets are awesome and in all the right spots.

    The hood like the body of the jacket utilizes that same stretch or elastic lining so it is extremely warm and comfortable.

    Let me know if you have any questions about this jacket or layering in general! I would be happy to discuss exactly how I layer for mountaineering, ski touring, ice climbing, or winter camping/hiking.

    The jacket seemed to be very well built and attractive. It had all the features one would expect from a high end belay jacket. My only complaint was the fit; the chest and underarm area were very tight. I ended up sending it back and purchasing the Haglofs Mojo instead (highly recommend). If this jacket fits you, I would recommend it. A medium did not fit my 39-40 inch chest.

    I can't say enough good things about the K7 jacket.
    First off, it's incredibly warm. I spent a few nighttime hours outside when it was about 5F and I was happy as a clam with just a merino tshirt and and an R1 fleece underneath.
    The stretch baffle stitching is super awesome–it affords a little extra room if you're tossing the K7 on over a shell and few other layers during rests or belays, and also provides some additional range of motion.
    I'm usually a size Small in Arc'teryx and a Medium in Black Diamond outerwear. The Medium K7 fits me perfectly–enough room for plenty of layers, but I'm not swimming in it. The sleeve length is perfect and it's your typical parka length, but the double zipper allows you to open the bottom up for belaying off of a harness.
    It comes with a stuff sack, and easily packs down to roughly 2.5L. It could probably pack even smaller with a compression sack.
    The construction is top-notch and I have no doubt the K7 will last me for years and years.

    Great down parka

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: XL

    First off, Mountain Equipment, regardless of what our friends across the Atlantic Ocean might think, does run on the small side compared to TNF, MHW and Patagonia. I'm a size Large in US brands but need an XL in Mountain Equipment all the way across the board, from the Crux tee shirts to the Chamonix Sweater, Eclipse fleece pieces, Vega jacket and finally the Annapurna.
    That being said, the K7 fits slightly smaller in the chest and arms than does the Annapurna.

    Warmth wise, very comparable to the Annapurna and more than the Vega. I'll give it higher marks than my MHW Nilas jackets too, but nowhere near the warmth of my MHW Absolute Zero parkas. Then again, there are not many contenders out there to outseat the Absolute Zero parka from MHW.

    Fabric seems robust enough to withstand the use cases I have in mind too. I wont be rappelling off any rocks while donning this jacket but instead using it for static moments in the mountains at the huts.
    The EXL system around the back, which is also featured in the Citadel jacket is a great feature along with the way the hood fits over a climbing helmet.
    Pockets are ample too. The front hand warmer pockets are nice and spacious too.

    This parka is really warm. Used for breaks on Mt Rainier down to about 9 degrees. I love the way the baffles expand and constrict based on the layers you are wearing underneath. I'd say the fit is a tiny bit on the small side. I'm normally a L in all jackets and this L fits a slight bit trim with a few layers underneath. Really it fits perfect for me. I'm 5'10 190. Makes a great pillow when you stuff it in a stuff sack too. Water bottle pocket and zipped pocket are perfect. ME nailed the design on this. One small improvement might be some velvety wrist cuffs like they have on the MH Nilas. Can't wait to really test it out below zero next winter.

    I live in Boston and this past winter was a rough one. I can't count the number of moments I was thankful to have picked one of these up for the winter months. The jacket is incredibly warm but I never got sweaty even when doing some brisk walks through the city. The fit is nice and athletic, which makes it a great jacket for the city. It felt very appropriate for winter in the city. Buy this coat!

    Materials and build are awesome. Fit is true to size, maybe a touch long/slim compared to some other brands. I'm 6' 190lbs and the XL is perfect. A bit extra room to move around and good coverage in the waist/hips to keep the cold out.

    Freakishly warm.

    I've been using one of these jackets for a year or so now. Barely heavier than a stitched through jacket but MUCH warmer.

    Things I like:

    Long Cut

    2 way zipper.

    Nice internal pockets

    Stretch Baffles

    The hood.

    Down Codex... ethically sourced down.

    It's often too warm for the Cascades, but who cares. You know you'll survive with this thing in your pack.

    (Also, the 750fp thing is an EU rating - it's actually more like 850fp.)

    I've owned this jacket for about 3 months and, if its dry, it?s my go to puffy. I can see this jacket lasting many, many years. Like many people, I don't baby my gear and this jacket has held up its end of the bargain. I've used it inbounds skiing, touring, and other debauchery in the mountains. I'm one of those guys who is proverbially cold and, before I owned this jacket, I would sometimes wear three puffys to keep me warm. Now, I throw on the K7 and shred. I own a couple other pieces of Mountain Equipment gear and the quality of this jacket matches everything else I've got. Top notch.

    Awesome belay/climbing jacket

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

    I struggle with down jackets, I want one that keeps me warm but doesn’t make me feel like Ralphie’s brother on “A Christmas Story.” It seems like most companies I have tried either load up on down or they don’t add enough. So you have to pick movement or warmth.

    The K7 does a really good job of giving me both worlds. They use a 750 Down fill that has a dridown treatment with a pretty water resistance outer shell material. Under the arms there is just a little bit less down, still down but not as much as on the chest or on top of the arms (there is still down and never once has the underside of my arms been cold). This is nice when you want to climb in it. The jacket allows you full movement of your arms without restricting you.

    The outer shell seems durable also. I have had it for about a year and there are no holes in it to date. Just last night I was rapping off a WI climb and had several times where there were funky raps that caused me to hit the sides of the rock with arm and I had the K7 on. Upon inspection this morning there is nothing wrong with the jacket. I think it will stand up and be worth the money.

    The hood ME also got right. It fits over a helmet allows me to move my head around freely and not be constrained. There is nothing I hate more than a jacket that doesn’t allow me to move my head freely and tires out my neck.

    I also love the large internal mesh pocket on the inside for a water bottle or gloves. It’s really nice to have such a large pocket to pop your climbing gloves into and keep them from freezing at the belay.

    Its warm it, it climbs well, has an awesome hood and good features. Of all the downs I have tried this is the best if you want something warm and is going to allow you to move when needed.

    ME like most all of their products that I have tried got this one right and I give it five stars.
