    Dynotherm Down Vest

    Unlike most down vests, the Mountain Hardwear Men's Dynotherm Down Vest offers core warmth that stays warm when wet. Mountain Hardwear's Q.Shield treats the down to retain its loft and warmth in rainy conditions. Double-needle stitched ripstop keeps the shell durable and long-lasting for years of campsites, hikes, and urban adventures. 
    • A down vest that pairs well with backpacking and camping trips alike
    • Q.Shield Down insulation resists moisture in light rain or snow
    • Dual hem drawcords trap heat close to your core on brisk mornings
    • Packs down into chest pocket for easy storage when the weather turns
    • Item #MHW00IU

    A little to long

    • Familiarity: I've put it through the wringer
    • Fit: Runs large
    • Size Bought: Medium
    • Height: 5'1"
    • Weight: 125lbs

    I Love the look of this vest but it fits a little large so i only use it for multi pitch climbing. It works great for that because it tucks down under my harness with out coming up and out. it keeps me worm with high winds and fits well with my base layer .

    Nice look, poor fit

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

    I've always been a MH fan and everything in a large has fit me perfectly until this vest. Its a good deal at $150 and I got it for 25% off. I'm 5'11", 185 lbs and wear a large in almost everything from all top gear brands, and one of my favorite pieces is my original MH tech vests in a large, that I've had for quite some time. I now also have a MH tech II vest which fits a little looser than my tech I, but not off enough to want to return it. The Dynotherm Down vest, on the other hand, was disappointing in it's overly baggy fit. The chest gave a little extra room similar to the tech II but abdominal area was absurdly baggy giving me room to add another 25 lbs of beer gut (I'm 5'11' 185 lbs chest 43 waist 34 inseam 32). I sent it back in exchange for a medium, and the 'gut' section was a good fit, but it was now tight across chest and in the arm pits. I sent the medium back as well and am waiting for the Arcteryx down vest to go on sale...

    had the same problem with a patagonia vest. I always wear larges just like you said. im also same exact size as you. 1" taller. Large in this patagonia vest had room for a massive beer gut. medium is too short. Not sure on the sizing and cut on some of these brands anymore? thought these brands were for somewhat athletic outdoor people. lol

    I have mixed feelings about the dynotherm vest.
    I found fit to be spot on pocket location etc.
    I primarily use the vest as an outer layer with 2 ems powerstretch jackets as base layers.Very lightweight and surprisingly warm. On severly cold days. Ill add a coat over the vest.
    The vest is very warm and lightweight.
    My only con with this jacket is with the ripstop shell. Keep in mind I am active but not hard on the vest, mainly used to kick around town.
    I find the nylon to be very thin(even for nylon)and does not wear well. The nylon has the look of something constantly rubbing against it despite the fact im very cautious with it. I did go ahead and purchase a second vest although I had to think twice, because of the wear issues.Ultimately I love the look ... so went ahead with a 2nd. I purchased both vests in Large because, I wear several layers underneath.

    Seems like a perfect down vest!

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: Runs large

    I gave this vest as a gift to my Dad, but have some feedback!
    The color on this vest is great, and the style is really nice.
    It's a pretty basic piece, but makes for versatile layering. You can rock it with a T-shirt on slightly chilly mornings to keep your core warm, or layer it thoroughly with other pieces for winter hiking, skiing, or any other outdoor activities. It's a pretty straightforward vest, and was what I expected from the photos.
    As others mention it does run a little big.

    Just What I Expected

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs large
    • Size Bought: Medium
    • Height: 6'0"
    • Weight: 180lbs

    I literally just put on my new Mountain Hardwear Dynotherm vest, and the fit is perfect. I heeded the advice of other reviewers and went with a medium instead of my usual large, and the fit is ideal. I am 6 feet tall, with a 41 inch chest, and roughly 175-180 lbs.

    I actually bought it primarily for cycling, because the cycle specific vests and layers I own always seem to leave me feeling cold, because I sweat a lot when I ride and am usually wet, either from sweat, or from the trapped moisture from the Goretex and such. So I figured if I am going to be wet anyway, I may as well be wet and warm! I live in Chicago and ride the bike path along Lake Michigan, and there is always wind chill, pretty much year round. I'm hoping this down vest will keep the chill out.

    A couple observations: I wore the vest over a Craft base layer, a Helly Hanson midweight layer, and a Gore thermo jersey, and felt snug but not tight. The length is great, it fully covers the lower back which will be a benefit while bent over on the bike. Also, the loft of the down doesn't seem to be overly full, which is good, since I will be being pretty active while wearing it and just want a little extra warmth. The neck is nice and tall, but does not chafe under the chin, and fits close but not tight at all. The elastic under the armpits seems perfect as well, not binding/loose. This is the first Mountain Hardware piece I have bought, and am very impressed with the quality and fit.

    I will update after I take it for a ride in a few days, in 45 degree weather with 10 to 15 mph winds off the lake!

    I'm a fit, in shape, 5'11", 180 lbs and the large gives way to a bunch a more beers in the belly. Basically, there is a lot of extra room with the large. The medium fits perf!

    Versatile and Easy to Pack

    • Familiarity: I've used it several times
    • Fit: Runs large
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 160lbs

    I recently started using this vest and have so far been very satisfied with the overall performance. I mostly use it on extremely cold ski tours and for downhill skiing in the resorts to keep me warm while sitting on the chairlift. At 10 oz, it keeps you incredibly warm for minimal weight and it packs down to fit into the smallest nooks and crannies of your pack.

    One of the major points I want to highlight is the Q.Shield Down which still maintains its loft and warmth even when slightly dampened. Multiple times I have been out skiing while it was snowing heavily but have noticed very little difference in the warmth I gain from the vest even after it has been slightly dampened. As a note, this does not mean that you can soak this vest completely through and it will still be functional, but the Q.Shield does help when you are out in rainy or snowy conditions.

    As for sizing, I chose a size L and at 6'0" and 160 lbs it is a little on the large side for me despite the fact that I wear an L in most other brands.

    Overall, this is a great vest and definitely worth looking into if you want something lightweight, pack able, and great for skiing!

    Functional and Stylish

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 6'3"
    • Weight: 180lbs

    I've been using this vest quite a lot through this fall and winter and am very happy with the purchase. At 6'3 and 180 lbs I went with the Medium, I normally go with Large on Mountain Hardware but when not worrying about sleeve length on my gangly arms Medium was the right choice for a slim fit (the only other MHW piece I have in Medium is the Ghost Whisper down jacket). I use it as both a technical layering piece while skiing and a stylish outer layer around town, here's a break down.

    1. Weight to warmth ratio. At 10 oz this is an easily packable lightweight vest. It's not Ghost Whisperer light (which is 5 oz) but that's why it's $100 less expensive. The vest provides just the right amount of warmth, day's that are cold enough to want more insulation I just go with my Ghost Whisperer jacket.
    2. Well organized. The hand warmer pockets are well placed with plenty of room, the chest pocket is a welcome addition that you won't find on the Ghost Whisperer vest, and internal drop pockets are also useful.
    3. Stylish. I got the underbrush/shark color and love it. It's perfect to wear around town in the fall and spring.

    1. Plume loss. This is the one and only reason I give the vest 4 instead of 5 stars. The down plume loss has not been severe, but I haven't been impressed either. I was hopeful that in exchange for the added weight the fabric would resist plumes sneaking their way out more than it has.

    Overall I highly recommend this vest. The plume loss has not been severe enough to upset me, I just think it's the one area that could be improved upon. If you've got the cash and are looking for something strictly for lightweight layering go with the Ghost Whisperer. If you want a technically functional vest that is also stylish and practical around town the Dynotherm is what you're looking for.

    Unanswered Question

    I would like to know why there is no choice for medium size for this jacket? There's S L XL XXL and they are darker or lighter whether you still have them or no, but the medium choice is not even there. Unfortunately, I think it would be the perfect fit for me. The green/black is the jacket I would like to order.
