Description

An ultralight down layer for weight-savvy backcountry purists.

Designed to outshine that old, bulky fleece layer that you’ve been lugging around in your pack, the MontBell Men’s Ultralight Down Jacket weights no more than a T-shirt and packs up around the size of a water bottle.
  • 800-fill goose down lofts easily allowing more body heat to be trapped between the feathers which keeps you warm
  • 15D, Ballistic Airlight nylon shell ensures durability without sacrificing weight
  • Polkatex DWR coating keeps out all extra moisture trying to sneak in
  • Single-quilt construction reduces weight and stuffs easily into your pack or pocket

Ultralight Understatement

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

First of all the understatement. This jacket is lightweight. For what it is intended to do, being a mid layer or a stand alone jacket for cool conditions. The Montbell UI down jacket does this quite well. I have the Indigo Blue color and it does not look too shiny to me. With the 800 fill goose down it is plenty warm for around town in most conditions I'm not sure that it would keep me warm in below 32*F. by itself, but it would be fun to try. Most jackets I can wear a Medium or a Large. This one I had to go with a Large.

Very thin and not very warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

We purchased the 'jacket' as a down sweater for a a July Washington State 7-day hike to wear in the early morning and in the evenings. It did not keep him warm. Compared to every one else's down sweater, his had very little down and the jacket was quite flimsy and not worth the $154 bucks. He had to wear his light rain gear over it to stay warm. We returned it when we returned from our trip.

Superlight and good insulation

  • Gender: Male
  • Familiarity: I've used it several times
  • Fit: True to size

I've had this for about 1.5 years, but I live in LA so I don't get to wear it that much other than ski trips. It's a really nice piece and the weight-to-warmth ratio is amazing. It also looks really good and packs incredibly small. You can just keep it in your day pack 100% of the time and never even know it's there until you need it. My only minor critiques: (1) it needs to have at least 1 pockets; (2) it would be great if the jacket folded into itself like the Nanopuff; and (3) it could be about 2" longer in the torso (at least for me)

MontBell Ultralight Down Jacket - Men's

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

Love, love this jacket, light, warm and true to description. Will be great as a spring jacket too. Being a lady and this a men's jacket I had at first purchased a small and had to return and get the medium.

Perfect

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

I LOVE this jacket. You really forget you have it on it is so light, but you remember because it is so warm. I always throw it in my pack if I think there is a chance it will be cold. AN 8 oz insurance policy. I am 6' 2" 170 lbs and a large feels just right. I appreciate the long sleeves. Body is short, as is normal in a jacket, but not excessively. I also use it i my office at work, where I usually freeze in winter (LEED Platinum building, so too cold) and it makes all the difference; A sweater left me cold. I appreciate that it has fewer sewn through baffles than the silly stylish jackets around these days, and that may help explain its warmth for so little weight. Details like the slightly elastic cuffs and stuff sack are nicely done. Finally (and this is silly) the green color is absolutely beautiful, just like the photo. Love this one so much, I'm thinking of getting an Extreme Light as well...

800 fill down = WARM

  • Familiarity: I gave it as a gift
  • Fit: True to size

Bought this for my Dad for Christmas. What a perfect gift seeing that he loves down jackets! He is very happy with it. Said that it's slim enough to layer easily, yet extremely warm. That's about all I'd need to hear to be convinced to buy this awesome jacket! Been chilly lately? Look no further. The answer is right here.

Love this Jacket!

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

I also have a Patagonia nano puff and a Outdoor Research down sweater but this is the one I grab the majority of the time. Went on a long snow shoe trip last weekend in 15 degree weather. Wore a long sleeved t-shirt and the MontBell and was perfectly warm, even unzipped the jacket several times during the day. It's super light weight, form fitting and very wind resistant. I'm 6'1" 178 lbs and the large fits perfect. Highly recommend.

Light jacket

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

This jacket is incredibly light and packs down to nothing. This is definitely not the warmest down jacket on the market and it's not supposed to be. Perfect for long backpacking trips and ounce counters. I can pretty much use this as a stand-alone warm layer down to about 40 degrees, and I layer it with fleece, wool, or a waterproof shell otherwise (it is great on top of my base-layer in the winter when moving around). I have worn it bushwacking and not had any tears or lost feathers, but I would be extra aware of snags in these circumstances as the light weight outer material feels delicate. I am 5'10", 165 lbs, and wear a small (form fitting). If I wanted to layer underneath it, I would have gone with a medium, but I tend to layer over it. I wish it cinched at the waist sometimes, but again, that would sacrifice weight. Overall, this jacket is a steal for the weight and warmth, and I get everything I need out of it.

Warm Jacket

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

Great jacket, nice and warm. It seems to fit true to size. I haven't had long enough (just a couple months) to speak on the longterm durability. But so far it's great. No feathers coming out as of yet.

My favorite mid-layer

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

I have used this for 3 years now and it is definitely my favorite mid-layer. It even works well as a stand alone layer, breathes pretty well and is pretty durable.

Unanswered Question

Can someone please post a photo of themselves...

Can someone please post a photo of themselves actually wearing the jacket? I'd like to see the fit. Thanks!

Perfect

Exactly as described. Very lightweight down jacket that should be even warmer when paired with a waterproof shell.

nice but not warm

  • Gender: Male
  • Familiarity: I've put it through the wringer

pros: very light, packs down super small, great for insulation on day hikes.
cons: not warm enough for nights camping in fall; definitely inadequate <30f; low fill wt - only 2oz - so though it is 800 fill, there is not enough of it to give adequate loft. my marmot wind shirt is way warm and still my mid layer for ice climbing.
only get this jacket if using when >30f

Responded on

Your rationale for giving this jacket only 3 stars is puzzling. This is one of the lightest and most compressible jackets you can find in a jacket with THIS much insulation. Like every single other jacket I am aware of, it does not provide enough insulation for some applications and provides too much for others. There is a temperature range where this jacket is effective and that range varies from one individual to the next.
It is NO reflection on the quality of the jacket that it is not suitable for the uses you happen to want to put it to and that should not be reflected in the ratings.

I'm curious. I don't layer with down when...

I'm curious. I don't layer with down when packing or climbing regardless of temperature (although I don't do much below zero) because sweat vapor eventually saturates the down and causes it to lose it's insulation value. Instead I use fleece and/or a MontBell UL Thermowrap suit (Exceloft fill). For those of you who report using this jacket as a layer, do you use it for extended, moderate to strenuous activities?

Responded on

I used this as a layer under my Montbell rain trekker while I was biking the northern parts of the Great Divide MTB route and I did not have any troubles with the down getting wet from me perspiring. This could be because I was using it in the low 30's to high 20's but regardless I didnt have any issues and I would be riding for hours at a time. Only when it started to down pour and the water got to to it did I have any issues. Then like any down, it was useless.

Responded on

This is my favorite layering piece. Its super light and packable so I can take it everywhere. It even works well on it's own and is surprisingly durable.

The best!

  • Gender: Male
  • Familiarity: I've used it several times

Love this jacket. Has a better cut and feel than the Patagonia down sweater - feels a tad bit warmer as well. The Paprika is a much better color than the photo would indicate. I layer an Arcteryx Beta SL (3 seasons) or Beta AR (winter) over it. 6'3" and 210 lbs - XL is perfect.

Great!

Jacket is ultra-light, easily packed, and warm as a fur coat. Fit is perfect and true to sizing.

anyone own this new color "dark blue"...

anyone own this new color "dark blue" trying to determine actual color. Is the gunmetal going to be shinier? Does the wrist still have an elastic stretch to it? Trying to decide on a light down layer that isn't shiny but seems all are like that now...seems all I can find is the EB microtherm shirt.

Responded on

I just bought the gunmetal and it's not as shiny as you'd think - it actually has close to a matt finish to be honest. I even wear it with a pair of jeans and sneakers when hanging out with friends, it looks great. I tried the EX Light at the same time as trying this version, and the EX Light looked like a trash bag in comparison.

The wrists do have some elasticity to them.

I love this jacket - you can wear it as an insulation under your shell, or wear it as a casual jacket in the colder months.

Responded on

I agree with the above review. I tried on the Ex light at the same time and while it's close to black, which I like, the main difference is no pockets in the Ex light. UL has pockets, feels the same, and is cheaper. Was a no brainer for me. You won't notice a difference between the 800 vs 900 fill.

Got what I expected

I did quite a bit of investigation before I purchased this product. I was looking to replace my heavy fleece to reduce my backpacking baseweight. I've had the chance to use the jacket on both short and extended backpacking trips and it has performed as I expected. I'm getting the equivalent or better warmth at less than half the weight. It works well for those chilly mornings and evenings.

I considered going with the extra light version but am glad I didn't because I find the pockets useful. I'm not too crazy about the shiny finish of the shell but I bought it more for function rather than style so I'll live with it. I haven't had any issue with shedding yet - only one feather that poked out and I used Mont Bell's suggestion of pulling it back into the jacket.

I'm 5'11" and 165 lbs and found the medium to fit me well. I'm able to wear a base layer plus wind jacket underneath with no issue. I like the snug fit as it helps to keep heat in.

Overall I'm very happy with this purchase.

Responded on

I am 5'11" and 150 lbs, if would like to use it as a layer under shell for extra warmth, should I pick meduim or small? thanks!

Responded on

I would stick with the medium. I think the small would restrict your movement too much and the sleeve might be too short.

Responded on

how well will this jacket fair in a compression sack with other items of clothing? (concerned about feathers popping out after repeated subjection in and out of the compression sack. I am considering taking warmer clothing in a comp. sack just to save on space.
