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

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

  • 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

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?

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.

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.

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.

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.

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.

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!

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

How shiny is this jacket? anyone have pictures of the Sepia and Dark Navy? I know the 15 denier is going to have sheen but don't want the trash bag look. Thanks.

The UL Down is not too shiny. You should be happy with it.

It has some shine to it but it's not overbearing. For function you can't beat the combo of price, weight, and brand.

It's a great garment, but my wife's Fall 2011 version came with a nicer interior (different color than the outer shell color and interior drop pockets).

Same great quality, loft, warmth as previous versions. However, I was hoping for additional 'storage space' (i.e. interior drop pockets). I assume MontBell wanted to cut down on weight/packing ability by not including this added material (?)

6'2" and 170lbs.: The Large flared out at the bottom a bit. This obviously won't matter when wearing it under a hard shell, but might get drafty on it's own.

I'm glad I decided on this 'less expensive' version of MontBell's down jacket lineup compared to their Ex.UL Down Jacket which was significantly more expensive and didn't even drop below my belt-line when worn with a T-Shirt underneath (size Large).

Me: moderately fit, but kind of barrel chested, with a small amount of 'beer weight' :)
5'10" 185#, 42" chest, 33" waist, 16.5" neck, 72" wing-span, avg. torso length. Generally a 'medium' shirt size. At the recommendation of the MB size chart I purchased a large in primary blue.

I wrote a long review, but erased in favor of the TL;DR version:
My new go-to jacket- LOVE IT.
weight is very amazing
can compress to well under 1L volume (0.6L?)
Perfect for freezing temps
Layers well for colder
Quality construction
Stuff sack is stupid- jacket would easily fit in huge hand pockets, but not capable due to non-reversible pocket with single sided zipper pull.
Crinkly-Noisy
Shinier than I'd like but not bad.
Blocks wind well, it holds its own, but it's not windproof. maybe on par with 'windblocker' fleece
Cut is generous- If seeking a close-cut 'over a baselayer only' insulation, size down. I have room for a 200wt fleece under mine (recommended size)
Edit: my Large weighs 241 grams (8.5oz) while in the stuff sack

Those are the big ticket things I noticed. overall, fantastic jacket.

In the late summer and fall, I wear it alone as a light down sweater, in the winter I wear it under my shell for extra warmth. It is crazy light has a great cut and looks good all by itself. I have had it for over a year and have had now issues with leakage. It isn't the warmest jacket, it is light lightest. That is sorta the point.

Didn't buy this product on backcountry. Totally my bad since backcountry stands by their sales while Montbell does not. This product leaks down more than usual and rips super easily. Totally made to be in an inner mid layer, but you still have to baby it. Buy something else.

I have to totally disagree.

I am a Scoutmaster of a very active Troop. I have one of these and it is my GO TO jacket for all but the coldest of months in Missouri. Yes its not made out of ballistic nylon and you got to watch that an ember from the fire doesn't make a hole in it, but you have to do that with anything. Yes if its nasty I put a hard shell on over it. It is what it is, a SUPER lightweight coat. People are shocked at how small it is, stuffed in its sack (which stays in the pocket when not in use). Contrary to the description its much smaller than a water bottle (1L) when stuffed in the sack.

I am right now shopping for one for my own son.

I would also have to disagree with this review. Mont Bell has a lifetime warranty that covers excessive down leakage. Also I believe the name of this jacket is the UL down inner so yes it is considered an inner. I have had one of these for years and have worn it as an inner and outer and have had no issues.

I had an issue with Mont Bell not warranting their products. Once it is "used" in their words, they will do everything possible to say it was your care of the jacket that caused the issue.

I also disagree with this review. I also have had this jacket for almost a year and wear it every week. I have worn it pretty much every day since mid September. It is a down sweater, not a bulky full on jacket. I wear it alone but also with a Gore-Tex shell. It is very light. I have had very little down leakage.

I absolutely disagree with this rating - lightest, most comfortable, warmest for the weight of the ultra lights have purchased many for family members and will purchase more - I have 4 one leaked a bit but once i washed it leaking stopped - I wash in cold water, spin, hang and fluff have one I have had for 5 years still great

i have had the jacket for two years, where fairly regularly from fall to spring and it has held up. no tears or leaking of feathers. one major flaw of this jacket is that it is not warm in winter weather <30. by comparison, my marmot wind shirt (i got the down hoping to replace) is much warmer and i still ice climb with the windshirt, not the UL.
UL advantages:
1. light, stuffs into small sack
2. great for day hikes where you want a little extra insulation on hand
UL flaws
1. not adequately warm for nights camping in fall
2. 800 down, but low fill wt, so not enough down in my opinion
