2013 Kelvinator Down Jacket

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

I bought my jacket last season, as a Close Out from the prior year.
I love this jacket. I would give it Five Stars if it wasn't for my jacket being Feathers and Down. Either way, for the many jackets I have had in NW Montana, this would still be the warmest. I've worn it out in Sub-Zero weather and been plenty warm.

Use it on Elbrus mountain in july. Was very strong wind, but feel fine in this jacket. Ventilation is not very good, i was wet sometime. And not enough length. Felt cold on back when sit down.

Quality is good.

For winter alpinism need something warmth. Especialy in Russia.

PS. Sorry my English. =)

Great jacket. Very Warm

    Bought this as a puffy to wear while standing around and belaying during ice climbing in the White Mountains of NH. Plenty of room, Hood fits over my helmet, zipper come right up to my nose, very warm and will compress down smaller that the compression sack it comes with.

    Good coat, just a little tight

      I was torn between this and the Marmot Ama Dablam. I ordered both in a medium, but the Kelvinator was just a hair tighter in the pits. I'm keeping the Ama Dablam as it's a bit bigger, and has longer sleeves. I'm 5-11, 170lbs. Wider shoulders, longer arms. If you're on the Med/Lrg fence you might want to size up. I tried on a Large MH Ghost Whisperer and it fit fine...

      Random sizing info, but maybe it'll help you.

      I want to sleep in this jacket every night

        I am a woman who was surfing all my favorite gear sites for the perfect down jacket in vain, when, this jacket appeared. I am a womens S/M 5'4 130 lbs and ordered the men's small. It's a little big for me but that makes it prime for layering. I have never loved a down jacket more. It has the perfect amount of down fluff so I am still toasty warm at high altitudes on snowy nights without feelings like Ralphie's brother in A Christmas Story ("I can't put my arms down!"). And it's super compact when I stow it in my pack. Overall...super freakin awesome

        Cold ? What cold?? ....

          So they say it's cold outdoors huh! well it isn't cold enough. You know those cold chillers with the bone chilling humidity well; let's just say they won't be bothering you anymore.

          I've had this jacket for two weeks now and it's been in service ever since the day i received it. It's much lighter than i expected but the warmth is just great, i've used it as a mid-layer, jacket etc.. I don't even feel the wind.
          last thursday it was about -15 c and all i had under was a t-shirt i went out to the lake to test it out i was warm the whole time. yesterday we had 35-40 mph winds and we went for a walk with the dogs i was feeling great.
          My original concerns were how resistant the ripstop was, how warm and how water resistant\windproof this jacket was and let me tell you i have been pleasantly surprised. it is exceptionally warm, it repells water lightly, i havent felt the wind nor the humidity. I purchased this jacket for the humidity factor i was tired of freezing and getting the chills and i don't regret buying this jacket. overall 5 stars and it looks great in black.

          The only thing missing were my goat stickers, but the shipping was very quick.

          Great jacket, good fit.

            Although it is pricey, I love this jacket. I started with the large and decided that it was a bit baggy in the waste (6'1" 165lbs) and traded it for a medium, which fits nicely. It could be a tiny bit more trim in the waste, but not bad at all. I got the Kelvinator voltage green, which I think looks nice -not too limey and not too bright.

            Great buy!

            Warm light jacket but be careful

              Awesome jacket. I wear it biking around town, hiking, climbing, pretty much everything. This is my first down jacket and it's great for how light it is and can stuff down real well. Only problem is it is rather fragile. A lone branch caught my sleeve and ripped a hole releasing all the down in the compartment. I did my best to stop it and used some electric tape to patch it back up but I'm still uneasy about anything else catching it again. Also since it''s down it doesn't perform well when wet but that gives me more motivation to move around and warm up. Other than that it's a great buy!

              LOVE IT!

                This thing is amazing! I needed a light, small-when-packed down layer for backpacking and this is it. I have a First Ascent Guide jacket with 800 power fill for when it's just stupid cold out, but that was a bit bulky. The Kelvinator's hood and elastic makes it feel like a custom fit just for me. I was debating a jacket with a hood, but I'm glad I got this because it's just so much more convenient and warmer when standing around in the wind. I layer a Marmot Tamarack (awesome) jacket over this, and can even tuck the hood down and out of the way if I want to only use the hood on my shell. I don't notice it's there, plus it's like a built-in neck gaiter for the back of my neck. Just too much good to say about it. Stole one online for 142.95!!! Very difficult sizing. I'm 5'9", 150lbs, no gut. The small and medium were close, but I finally chose the medium since the small jacket dug into my arm pits - uncomfortable with layers on. Other than that, the sizing was almost identical. My cold winter, "standing around" setup is a Capilene 3 half-zip, 200wt fleece jacket, plus this = cozy blast furnace!

                mar2966897: I'm the same size as you, and wear a medium in my other MH jackets. I'm looking at the Marmot Tamarack as well. What size do you have the Tamarack in? I tried a small on, and it fit well for just a base layer and fleece, but not sure if this Kelvinator could fit under it. Do you have a medium? thanks in advance!

                Perfection...... Check Please!

                  Perfect mid-level down jacket. This jacket can handle most conditions you encounter. Extremely light, comfortable, and warm. Stuffs down to size of a Nalgine bottle. Went with the voltage color, can see hints of the down throw it, but I personally don't mind that. Size fits true to size. Also not too puffy so can throw your shell over it for the slopes or if conditions get nasty in the backcountry. This is my go-to jacket on a cold day out in Sun Valley!

                  Get Down!

                    This is the perfect down hoody. And one of my favorite items from MHW. Fits and feels comfy like a sweatshirt, but it's really warm. I usually just wear a T-shirt underneath for around town. And then you can pack it up small and keep it in the pack in case you need it. It's also very lightweight, not big and bulky like some down jackets of similar fill.

                    If I could only have one puffy this would be the one.

                    Only downside is the price

                      First I need to get something out of the way as it's the reason I'm torn between giving it 4 stars instead of 5. I really wouldn't expect this to retail for the full MSRP despite how great a jacket it is. If it had 800+ fill instead of 650, or slightly more fill, [EDIT: Or if the outer fabric were more robust; 20D is just too thin], it would come closer to justifying the price tag. Comparable jackets can be found for a bit cheaper. Marmot, Montbell, Outdoor Research, and even Eddie Bauer (First Ascent Downlight Hoody is a GREAT jacket that is almost as warm despite its much lower weight) come to mind.

                      OK, on to the good. This thing is a great light-weight hoody-style down jacket. My plan is to use it for layering and it is exactly the right size for that job - not too puffy but puffy enough to give some serious warmth. It will be hard to find a better jacket for this role. I'm 5'6", 140 lbs, 32 in waist and the medium is absolutely perfect in every dimension. A shell fits easily on top and it can accommodate a base and a fleece layered underneath. The hood hugs my head very well with no additional adjustments. At present there is no indication of down leakage however I haven't put it into its stuff sack either so I can't attest to how down proof it is. Overall it's a long way towards being a full jacket on its own yet only so far as to not preclude it from a role as a light-weight layer or stand alone piece.

                      A final note: This has 4, not 2 pockets as BC seems to indicate as I write this. On the inside there is a small pocket located on the upper-left front as well as a large mesh pocket on the lower right front.

                      [EDIT 3/26/2012] I just noticed something that irks me incredibly. I already have a problem with the 20D outer fabric, as I worry this jacket will wear out pretty quickly. I just today noticed that the inside of the jacket seems to be lined with a 30D material! It may not be 30D but it looks identical to the 30D MH puts on its Lodown jacket, and it's thicker than the external material. If you're going to put heavier material into your jacket anyway, why not put it on the outside?? Sheesh. Knocking a star off my original review for this.

                      i'm thinking of getting one of these but how small does it pack down to? fist size or bigger?

                      Best Answer

                      Probably not quite that small. It's only 650-fill, so it's denser than some of the superlight jackets out there, and you can't compress it too much or it'll damage the down and it won't loft up again. I used to have the MH Phantom, which was a similar jacket to this one, and based on that I'd say you could compress it down to about 2/3 the size of a Nalgene bottle. Like a Chipotle burrito, roughly.

                      Can the kelvinator down jacket be waterproofed, if yes does it last very long.

                      Dave. Unfortunately, this jacket cannot be waterproofed. In order to do so would involve taping the seams somehow and making the fabric waterproof with some sort of laminate or coating. If you are looking for a waterproof down jacket or waterproof insulated jacket in general I would suggest the Absolute Zero Jacket from Mountain Hardwear or Gravitor Jacket from Mountain Hardwear as well. The Gravitor would probably be the closest thing, insulation-wise, but it is made utilizing our Thermic Micro synthetic insulation instead of down. I hope this info helps!

                      What is the rating for temperature. Are the sleeves nice and long???

                      Gail. Unfortunately, the jacket does not come with a temperature rating. This is mainly due to the differences in metabolism from one person to the next. What I can do is give you the amount of down that is in the jacket. In a Men's Medium there is 176 grams of 650-fill down. The more down... the warmer. You can use this number to compare warmth between jackets and it is probably the best number I can give you. The sleeves are not overly long... but, they are long enough! I hope this info helps!

                      I am looking to get the Kelvinator jacket...

                      I am looking to get the Kelvinator jacket but am concerned on size. I owe the MH Windstopper Tech jacket size medium and it fits me perfectly. However, I bought the MH Chillwave Down Parka size medium and the sleeves were WAY too short and now need to return. I am about 5'11" and 170# athletic build with slightly wider shoulders but not huge, but i think that might be why the chillwave didnt fit.

                      Any advice on the Kelvinator fit? I dont want to be swimming in a large if i go that route, but I dont want to have to go through another return... I mean winter is already here.

                      How does this jacket hold up in the rain?

                      The Kelvinator Down Jacket is an insulation layer, filled with goose down. So, subjecting this jacket to anything beyond a short period of drizzle, would totally saturate the insulation. Down doesn't insulate when wet, so if you are in the backcountry and depended on it to keep you warm, you would be out of luck. I would definitely want to pull on a dedicated rain jacket OVER the top of this thing. Hope this helps you, Sam.

                      Shawn Weede... that is the FILL type of the Down in the Jacket but not the AMOUNT (in grams) of down in the jacket. For that answer, brian, there are 176 grams of 650-Fill Down in the Kelvinator Jacket (size medium.) I hope this info helps!
