Impressive warmth without the weight.

Whether you're starting your approach, gaining the ridge, or summiting, the MontBell Men’s Ultralight Down Inner Parka's 800-fill down is an ultralight insurance policy against the cold. At just over seven ounces, the Inner Parka definitely won't break the weight budget for your fast-and-light trek; since it's packed with 800-fill down insulation, the parka provides as much insulation as your bulky heavyweight fleece. And if the forecast calls for rain or snow, fear ye not; this jacket comes with DWR coating that maintains its water-repellent properties for up to 100 washes.

Super Lightweight

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

This is a great down sweater to layer under a shell when in the backcountry, it is super lightweight and very warm when under a shell. On its own though the wind gets through it and I am terified that I am going to tear it on something or burn it on the stove. Still a great layer if you're trying to save on grams and will be using it under a shell.

I am 6'1'' and 165 lbs and it fits great.

Warm but fragile

I quite like this parka. It's good for around the house, and going to the shops. It's very light and very warm. The cut and fit are great too. People comment that it's like a sleeping bag. I think that's because of the nylon shell, and how soft it is.

Unfortunately, it's as rugged as a sleeping bag... I wore it under a raincoat and had a 15 kg pack on, and it damaged the fabric high on the back. It stretched and created some small holes in it. The other issue I have is with the down coming out through the jacket - i'd count at least 12 feathers pushing though in the first week or so. The advice that came with the jacket, was not to pull them out but to push them back in. This is nearly an impossible task when it's near a seam and it too time consuming and frustrating. So I've been quite annoyed at such advice and see it as a design flaw.

I recommend this jacket for uses suggested above, but have reservations for many other practical uses such as hiking. If I were Mont-Bell, I'd redesign the jacket with a thicker nylon or some inner fabric that the feathers can't work though so easily.

Oh, I'm 6' 2" and bought the large.

Mont Bell UL Inner Parka

I have had this for 2 winters.

This is what it is labeled as, an inner parka, good down to around 25*-30* with no wind and 2 layers underneath. Sitting around to medium activity.

On Windy days/nights, better have a shell.

Too warm above 40 with a medium base layer.

Pockets are prone to catch snow, cause they are open and shallow. I sewed a zippr on both.

Runs small.

It rocks

I love this piece. It is exactly what I was looking for - something lightweight and packable for Spring and Fall trips where my winter puffy is overkill. Something that is small and light that mostly lives in the pack until you need it. I had on a recent White Rim mtn. bike trip where the weather deteriorated from the forecast and it totally saved my ass. I was warm, even though it was cold, windy and raining on and off. One thing that surprised me is that the hand warmer pockets don't have zippers. It hasn't been a problem, and in retrospect, it is designed as a layering piece, so no zippers makes sense. I just didn't expect it. All in all, this piece rocks - and in earthy tones too...

The velcro tab rear hood adjuster. This is invaluable in my opinion, as I cannot stand having a hood that obscures my vision. Paired with a ball cap, a beanie, or by itself, the insulated hood provides a great deal of additional warmth

Mont-Bell UL Down Inner Parka

I decided to swap my beloved UL Down Inner jacket for the hooded, Parka version. I will solely miss the jacket, but I think the parka will be a fine replacement...

First Look: UL Down Inner Parka

I just received this jacket yesterday in the mail. I am actually replacing the regular Down Inner jacket with the parka simply because I felt like I might need the hood. I am planning an AT thru hike which is why I decided to go with the parka rather than the regular jacket.
I got the XL and it weighs 9.7 oz on my scales in the stuff sack, with the stuff sack actually being 0.2 oz of that total weight. As far as fit, it fits me the same as the jacket version, only it has a hood. I am 5'10" and 200 pounds and the XL leaves plenty of room to layer my Capilene 2 long sleeve and my R1 under, although it doesn't feel baggy by no means when I am just wearing a t shirt. As well, it layers under my GoLite Tumalo jacket without compressing the down and lowering the warmth factor!
The hood on it is quite baggy, but it has an adjuster on the back which enable me to adjust the hood back, as well as an elastic cord with a plastic/rubbery cord lock on each side of the front of the hood. All of these adjusters allow the hood to fit comfortably, whether with or without a hat/helmet.
It does have a draw cord in the bottom which allows the bottom to be sealed off from the wind, but I am probably going to remove that and save a little weight (even if it is 0.5 oz) and I do not plan on using it anyway.
The one thing I do not like about this jacket is the color. The brown just doesn't cut it for me and the Rust color was only available in Small, which I am not... So, I went with the Olive Green. It is army green. And I was really very happy with the color of the jacket version, black. I wish that this parka was also offered in black. And while color is not a big deal (in the backcountry) it does have it's affect on how well I like something. I am hoping that the Army green grows on me, if not I will swap it for another color at the end of the year when they start carrying the jackets again. It's not like I will get to use it before then anyway.
Overall, MontBell knows how to make a jacket. These jackets are above and beyond the other jackets I have tried and highly recommend any of their jackets. These things are soft against the skin, and so light that it will feel like a puff of warm air is following you around rather than wearing a jacket. As well, this jacket with it's wispy 15D nylon shell will block way more wind than my NF Softshell...
Bottom line, if you are considering, stop and just do it. You will be happy you did!

Amazing piece

Just received this inner parka a few weeks ago and took it into the smoky mountains for a 4 day backpacking trip on the AT. it's early in the year and temps hovered between 27-33 degrees with strong winds. Every rest i pulled this out of my Nalgene bottle on the side of my pack and kept my body temps very warm. In the evenings as it cooled more i had brought a Patagonia Nano storm (their nano thermal built into a hardshell) which is ultra warm as well. I never even unpacked it. The Montbell kept me toasty without a firepit around all the way til bedtime. I really like the fact that this truly feels like a long sleeve shirt, has a great fit, and i made sure to get the hooded version and i'm glad i did, if you get any chill down your back just pop the hood and all the heat gets trapped in nicely. I'm back in Chicago and throw this on over a plain cotton TShirt and in 30 degree temps with no aerobic activity i stay warm. Blocks out high wind and the hem cords at the waist and around the hood allow this thing to be fitted perfectly. i'm 170lbs 5'11'' and the Medium is perfect. Haven't had to use it in any wet weather so i can't speak to the water shedding ability.

How does the U.L Inner parka compare to MB's Alpine Light Parka? Warmth to weight and durability?

Best Answer Responded on

This has 2.5 ounces of 800-fill down versus 4.3 ounces in the Alpine Light Parka. This is also a 15-denier ballistic airlight nylon shell versus a 30-denier shell in the Alpine Light.

This weighs 9.0 ounces in size Medium (the BC sidebar is incorrect; it's the UL Inner Jacket that is 7.3 ounces), and the Alpine Light weighs 15.7 ounces (also in size Medium).

Warmth-wise they tested within 4-5 degrees of each other. The Alpine Light is also more fully-featured, with interior drop pockets, a microfleece-lined collar, heavier zipper, and zippered and fleece-lined handwarmer pockets.

Both are exceptional pieces; I think it comes down to what you need.

Hope that helps.

Super Light & Packable

I was looking for an extra light jacket to toss in my pack. Compared this to similar items from Patagonia and Mountain Hardware and this won the weight issue hands down. If it weren't for the warmth you can't even tell you are wearing anything at all. Down shedding is a concern with such light fabric but I think I can handle it with some extra care.

How does this compare to the Western Mountain Flash in durability, down loss and fit? The Western Mountain should be warmer 3oz of 850 fill vs 2.5oz of 800 fill but the price difference is pretty shocking.

This jacket vs. a hooded MH nitrous ... who's going to win?

Best Answer Responded on

Terry, you can't really compare this to the Mountain Hardwear Nitrous. This jacket is very lightweight and the MH is almost double the weight. Different class of jacket IMO.

Great layer piece

This is not a sit-in-camp puffy; it's for layering, or if used as your primary insulation and it's cold out, for keeping you toasty when you're moving. It has half the loft of the Light Down Parka- but is remarkably breathable. If you're looking for a piece with a lot of loft and a groovy michelin-man feel, go with something with much higher loft.

The cut is athletic, with front pockets, a cinch cord at the waist, adjustable hood (which I have fit a climbing helmet into), comes with a stuff sack. Construction is sewn-through. The fabric is tissue-soft, does not repel water at all, but breathes and dries very quickly. By itself this garment will block some wind, but won't block *all* the wind- for that, you'd want an outer layer of some sort.

It's light and compactable enough that it's always in my pack when I need it. It warms whatever you put it under up by a surprising amount.

How is the fit on this jacket, is it slim?...

How is the fit on this jacket, is it slim? I am 5'9" and 145lbs with a 37.5" chest which places me right in between sizes and I have no idea which size I should get. I assume a small would be a tighter, more comfortable fit, but I want to be able to layer a fleece underneath it for colder days. Suggestions?

Best Answer Responded on

James, I would say Medium, especially given that you are planning to layer a fleece underneath. This has a very athletic cut, unlike the Alpine Light Jacket or the Patagonia Down Sweater. On top of that, all the mont-bell stuff seems to run just a bit smaller than other brands.

I wear a size 40 regular suitcoat, which puts me at the top end of the Medium, but the Large is more comfortable, with a bit (not too much) room for layering, and comfortable enough to sleep in. It's not bulky, either, I can still layer my windshirt or rain jacket over the top.

Super Soft

I'm 6'1', 175 lbs and ordered the Large which fits fine w/plenty of room for some layering. I think the waist may have been too short had I gone with the Medium. Super soft and nice to the touch fabric and like everyone else has already said, this jacket weighs next to nothing, yet is a nice insulating layer. The 'open' pockets do allow for cold air to enter but unlike so many other reviews, THE HOOD IS ADJUSTABLE! In addition to a good insulating layer it also folds down extremely small which will be good for me to stash inside my pack as a 'just in case' I need some extra insulation item. Overall, a really jacket.

how does the fit compare to the patagonia down sweater series? i'm 5' 10" (170lbs) and my size large patagonia down vest is too big, wish i had a medium.

Best Answer Responded on

I wear a size Medium in the Patagonia Down Sweater, but a Large in this and all the other mont-bell stuff. At your size, you might even fit in a Medium in the mont-bell stuff; I would try both sizes if I were you. At 5'11.5" and 171 lbs., I prefer the mont-bell in Large, but I'm right on the cusp of a Medium. Hope that helps.

does anyone have a photo of how this jacket fits around the head, or a description, does it come over or under your chin. is there down behind the pockets. cheers

Best Answer Responded on

The jacket fits well around the head, with enough room and coverage to wear a ballcap or beanie underneath. It adjusts in the back with a velcro strap, and around the face with cordlocks tucked away in the lining. When zipped up, it comes up over my chin, giving me the option to leave my balaclava at home. No down behind the pockets. This is a great jacket...

I'm 6'0" and weigh 170; will the large be the right size for me?

Responded on

I'm 6'1" 180 lbs and the large fits me well. I can get a few layers under it, but it's not to big without layers.

You might be able to squeeze a medium, but probably not with layers, and I would think the arms and waist might be too short because the large is about right.

Best Answer Responded on

KLC, I'm 5'11.5" and 173 lbs., and I prefer the fit of the Large. I could probably squeeze into a Medium, but I like to allow a little room for another wool shirt if needed, and I sleep in my jacket, so I don't want it too tight. And the Medium will have shorter sleeves, which may not work for you at 6'0". Good Luck.
