MontBell Ultralight Down Inner Jacket - Men's - 2009 BCS

I love this jacket. Weighs less than 8oz, packs small, blocks the wind, and keeps you warm in a variety of climates. I've used this during 20 degree mornings and stayed warm while packing up camp and cooking breakfast. Fits tight and is made for layering as the nylon can tear with heavy abuse. I layer it under a marmot mica jacket when backpacking long distances or wear it as an outer jacket around camp. It is incredible how well this jacket can block the wind. I prefer the down over the synthetic version.

First, this is a layering item. This should not be the outerlayer. Wear a softshell or rain jacket over it. That being said, this is an extrememly warm jacket for something that weights practically nothing, and fits into an included stuff sack. I highly recommend buying one if you can find it.

My only complaint, there is no latch, or special pocket for the stuff sack. And because the material is so slick, it can easily slide out of the pockets.

Light, Warm, Packs small. So, no negatives whatsoever. Buy it.
5'10, 190lbs. Size L fits right.

I bought this for my boyfriend who is an expert skier and does a lot of backcountry. He loves it. It's light wieght and keeps you warm. Great for an under layer on cold days.

This jacket is both light and warm. I've used it on backpacking trips, around town and it's great to stuff in the backpack and use when belaying at the crag or ice climbs. Can't get any better.

This will be the warmest lightest layer in your arsenal. Under a hardshell and over a base layer I have been comfertable down to 15, and with a few more layers I would take it down much colder. It has saved me from hypothermia several times in the mountains. Definitely get the hooded jacket... it is much warmer! They fit tight to make them more thermally efficient, but it is not uncomfertable. If you like a larger fit then get a size larger than you normally wear.

This is a great jacket. There is nothing else out there that gives you this warmth for the amazingly lightweight. It is a no brainer in a layering system. It performs really well and holds up well over time.
This is designed as a layering piece so the sizing is meant to be trim. Depending on your size if you want it baggier than you might want to order a size up.

I wanted the parka but everyone was out of them. I got this instead. Its super light weight and packs down to nothing. No more heavy fleece for me. This is a great jacket but if I could do it again I would hold out for the parka.

I am 6' 4" with long arms and torso, 180 lbs. The Large, as opposed to XL, fits more athletically but is just long enough on the arms. By just long enough I mean that relaxed it covers my wrists, but when I stretch up, my forearms become moderately exposed. It also a little short on the waist especially with no hem drawcord. XL on the other hand, for skinny guys, is about an inch longer (farther down) on the waist and an inch longer on the arms, but significantly more baggy in the chest area, again with a drawcord this may be fixed (montbell inner parka has one) but is a little annoying for anything other than sitting around because its loose. Both however are warm especially including layering, and neither looks funny, it is more a matter of what the primary use will be.

This is a great jacket. Smooth, soft fabric is ideal for casual and sports events alike. Can't wait for cold weather so I can enjoy it!

I live in the Colorado Rockies and at 7oz I take this layer with me everywhere. Most the time it doesn't get worn because of how warm it is. But when the temp. dips well below zero I am very happy I have this with me. I spent a lot of time shopping for a down mid layer and for the warmth to weight ratio I found none better. I am 5'11'' 170lbs with long arms and the medium fits great and leaves enough room for a shell. I am very satified and talk this jacket up to everyone.

What is there not to like about this inner jacket,super light,super packable,super comfortable.WOW!!!

While I was heckled about it's space-suit kind of look, I was super comfy wearing this almost T-Shirt weight down jack-shirt-sweater around the lodge and up on the slopes. This is by no means summit gear, and the shell material thickness is not tough enough to wear as outer shell off-piste. I did find a couple feathers working their way out of a seam but other than that even on bare skin it was super soft and lightweight. Wear this around the camp/lodge or even at home on those cold nights, as a mid level layer, but not as an outer shell if you're gonna be out thrashing.

The MontBell Ultralight Down Inner Jacket is very light,warm and small. I like it ^^.

I live in Western Colorado where it can be cold, but dry. This is a perfect jacket for anything above zero for me. I have a short commute to work on my bike and it is perfect. It is so light, that it doesn't even feel like I have a coat on.
Can't wait to use it for a layer under a sturdy outer layer. Can't imagine how warm it will be.

The MontBell Ultralight Down Inner Jacket - Men's is the same weight as a T shirt! When stuffed, it's 2/3rd of a quart. You don't know you are wearing anything but you're warm. It's brilliant.

Love this UL jacket. Pro: It is warmer than a fleece jacket and my gosh it's light. Con: shiny, looks like a Mylar balloon.. don't know if that will tone down over time, or if it's the water-resistant treatment.

I own both the jacket and the vest. Montbell make the most amazing light stuff. I've packed this gear on many of my long distance ultra light hikes and it rocks. Like most super light gear you have to treat it well but it's gives so much back in return. Warm and cosy in a wicked light package. Amazing - highly recommended.

As with all Montbell stuff the sizing is small. Get a size up from what you'd normally get.

When I purchased this jacket, I knew it would be light and warm, but my expectations were exceeded. Picking it up for the first time is stunning. Wearing it is like donning a layer of clouds.

I am 6' 2" with a sizable chest and long arms and am extremely pleased with how well the Large fits me.

It seems a bit delicate, but this is to be expected. I would never bushwhack with this thing exposed. It is great piece for use in an lightweight layering system, however. Compresses nicely for packing.

the thing weighs nothing. the "R" value is out of this world. Weight to insulation this is a great value.

Great jacket. I went with the ultralight instead of the light, because I work in the middle east. It gets pretty cold here sometimes in the winter, but not enough for heavier 30D material in the light. The fit is just perfect for me. I'm 6'2, 200 lbs, lean athletic, and the XL is just right. I've had Large sizes in these puffies before, and while that was ok for just standing around, the XL is not much bigger, but provides a lot more room for movement through the shoulders. The cut is great, allowing a good range of bending over without riding up or sleeves coming up the forearms. I really can't say enough about this.

Really amazing layer.It fits perfectly and is warm. And its really lightweight. So much that it seems a fake. The only thing to improve, some zips under the armpits to balance the transpiration, but these will add weight and probably reduce comfort. I am 1.73cm and 82kg, and the M size fits perfectly.

I got this as a gift from my wife for Christmas! It is an amazingly light weight inner jacket that I wear under my shell while skiing in Colorado. It is the perfect fill of down to keep you warm but not turn you into the Sta-Puft Marshmello man. it fits great under other coats and looks great on its own. It even comes with a stuff sack that helps with storage. Graet jacket that I would recomend to you all...but I am gonna keep this one to myself in my circle of friends for the jealousy factor!

This makes a great alternative to a fleece mid layer jacket. Although, mine had some actual feathers in it, so it's made a few pin holes and i've had some down leakage, not a lot, but there is stuff coming out and sticking to the inside of my softshell i normally wear over this jacket. for the price, i would still buy it again.

The fit is athletic and medium is perfect for me. I am 5.6 ft tall and weight 164 pounds. This one is perfect for outdoor activities in not so cold weather and will replace your normal fleece adding no weight to your pack! If you are going to use it during the winter you will need some more insulation on top of this jacket but for what it weights it is in my opinion a very smart buy. Very nice indeed.

Light, stuffable, breathable...great to throw into the pack or to wear straight out of the gate. I bought this to put in my pack during ascents so I could wear it between my baselayer and shell on the way down when backcountry skiing, snow-shoeing, or while doing some ice climbing. However, I haven't used it for any of that yet...I've used it for camping, riding, loafing, and for running the dogs and it's lived up to every expectation so far...warmth without overheating or the bulkiness of some of the loftier down jackets. I compared this to Patagonia's down sweater and liked this one a bit more because it was less bulky around the collar and more fit around the waist. If this sweater fits too snug around the middle, I think the Patagonia version would be your baby! I'm 6'0", 155, have a 15.5 neck, 32 sleeve, and a 38 chest - I bought the small and it fits great (snug but not overly tight - great for layering). Can't wait to get a MontBell sleeping bag now!

Compare this to the Patagonia down sweater!

hey everyone i just got the ultralight and let me tell you it's great , it's so light i don't feel that i wearing one , so happy , one of this days I'll download a pic. come on all you freaks get on line and get one before there vanish just kidding ! not I'm not see ya! happy new year .Victor

i wear a 37.5 and the small was just too tight in the armpits, across the chest. although the small fits great everywhere else, the boxy shape of the torso in this jacket leaves anyone who isnt shaped like a 2x4 a bit squeezed!

I just sized up to the medium and i like the extra inch of arm length, and the ability to add a layer or two as conditions require. without sizing up, adding a light merino layer was going to be a challenge.

size up if you are right on the upper limit of this jacket's chart numbers.

the lowdown.. the medium is offered at 7.3 ounces and mine came in at 6.6 - i hope it isnt light on down.. but in reality i dont see how that weight could have been lost in the shell. and also, my 2yo montbell vest has more loft than this jacket brand new. so, i think i got jipped about 3/4 of an ounce.. if not for the weight discrepancy it would have been a 5 star rating.

I bought this for my boyfriend who is an expert skier and does a lot of backcountry. He loves it. It's light wieght and keeps you warm. Great for an under layer on cold days.

Extremely thin then it looks on webpage. you gotta pay attention to the word "Inner". coz in cold weather you really need something except this one. other then that it's really good.
