Would this jacket be suitable for Denali?...
Would this jacket be suitable for Denali? I own it and I'm trying to avoid buying a new down jacket for my Denali climb next year. I'm guessing it might be a bit too light, though.
The Montbell Frost Line parka is a great, warm layer that may be suitable for a Denali climb, but it's going to depend on the season and your other layering options. This is definitely on the lighter side for Denali climbs and if it's your first foray into high altitude cold weather mountaineering, I'd recommend investing the money into a more suitable jacket. I generally recommend Denali W. Buttress climbers have an outer parka with 225+ grams of 650+ fill down. This parka has 190 grams of 800 fill down, so it should come close to the same warmth, albeit a bit on the lighter side. I've seen many guides walk to the summit in their Patagonia DAS parka, but they've mastered their layering system and know how their body performs at altitude and in cold. If you've got a 80-100 gram synthetic mid-weight puffy for lower altitudes, you could always combine the Frost Line and that layer to beef up your layering system and increase your warmth on summit day. If you're planning on climbing in May the temps are significantly colder and you'll want to layer accordingly, but in July summit temps and nighttime lower Kahiltna temps can be as warm as 20-30 degrees Fahrenheit.
Is this jacket sewn-through or box-baffled...
Is this jacket sewn-through or box-baffled construction? On this site it says sewn-through, but on the Montbell site it says Box construction. My understanding is that those are two different ways to baffle a down jacket.
MontBell went all out and made sure this was box-baffles. No 'for looks' down jacket here. this thing is fully functional.
is good enough winter in new York?
is good enough winter in new York?
Definitely. Just keep in mind that it's not waterproof, so if there's a lot of snow or rain it'll lose its warmth.
it's also not windproof so you may need a shell on a windy day, or you might be too chilly.
Warm, soft, portable... perfect
- Familiarity: I gave it as a gift, but have feedback to share
- Fit: True to size
I gave this jacket to my younger brother as his xmas present, and he's absolutely loved it. It's definitely very puffy, but in a good, warm way. Every time I saw him this past winter, he had it on- even inside, because it's just that comfortable.
Yellowstone in February
This jacket could not get any better!!!!!!
1/2 a sleeping bag
- Familiarity: I've put it through the wringer
This jacket is everything I hoped, and more. It's lightweight has all the bells and whistles. Detachable hood is a feature I haven't used yet, but can envision the pro's of having that option. Stuff sack is a great size, and once stuffed the jacket can double as a pillow.
All in all I would recommend this jacket to all my friends, and even my enemies.

am looking for a good belay jacket while ice climbing. consider:
1. montbell frostline
2. OR maestro
3. OR incandescent
need to be:
1. warm in temps <20F
2. light weight, compressible/packable in small bullet bag while multipitch ice climbing
any suggestions on best of the above for this use?
they all have some good warmth. the montbell is the heaviest and is made with the thickest material. my only experiences with insulated montbell jackets have involved down coming out. i would go with the incandescent.
The description is confusing. it says...
The description is confusing. it says "Sewn-through, baffled construction". So which is it Sewn through or baffled?
It's baffled construction if you're still wondering
Utah Mountains--one year later
- Gender: Male
- Familiarity: I've put it through the wringer
This is a great jacket. I bought it as a fall-back shelter for prolonged outdoor adventures or for days when I'm out in the weather all day for work or play. I bought an XL, bigger than my normal L, to fit over the other layers I would be wearing.
It is too warm for hiking or climbing, but works well for camp, belay, or delays on the trail.
After two winter seasons of use I found it to be plenty durable; use normal cautions when wearing.
The other day at work I was stuck out in sub 20 degree weather for an entire day. At the end of the day when I was exausted and chilled, I put it on and powered through to the end, cosy and warm.
The jacket covers me to below my butt, has a great hood, and the arms are plenty long. Good use of down--no cold spots for me.
I would recomment it to a friend.

looks warm, and looks made well
Highlining in a blizzard with montbell!
highlining in a blizzard, this thing was perfect
This parka will really keep you warm. Proper layering in temperatures around freezing will be important and I haven't been in really cold temps yet, but I expect to be comfortable in it (and I'm ALWAYS cold.) I originally bought a MH Chillwave but the sleeves on it were too short. The sleeves on the Frost Line are plenty long (I bought a large and wear 35/36" sleeve in dress shirts.) I do wish it had an external chest pocket. Also, unfortunately this parka is made in China, which has already blown my New Year's resolution to avoid buying Chinese products. I guess warmth trumps principles this time. Very light weight, great down loft, great parka!
Good Jacket, but insulation was not spread evenly
I bought this jacket and was really excited when I got it because it lofted up so high at first. However one day when it got to be around 5-10 degrees with some wind I decided to try the jacket out while walking the dogs and noticed i was getting getting cold around my lower back. When i came back inside I inspected the jacket more carefully and saw that the bottom two baffles on the backside were almost completely empty of down. It was a huge let down because I love Montbell jackets. I have both the UL Thermawrap and the Alpine light down parka and absolutely love them. Who knows maybe I got a bad one, but I ended up going with the RAB Neutrino Plus.
Serious Weather Only
I love the quality and the amazing warmth but I am returning it. I gave it full stars because it is perfect for its intended use. I have a low tolerance for cold, but this is overkill for anything above 20 deg F. I need a jacket with a range of the low teens to 40 that can be layered. So a down jacket that is not baffled (one difference between a parka and a jacket I'm told) is better for me. I found that perfect (for me) jacket in the Marmot Ama Dablam.
How does this compare to the mountain...
How does this compare to the mountain hardwear subzero parka?
Quite a bit lighter weight - will be around as warm as the better quality down. If your using where weight is a concern and you will only be wearing intermittently, definite advantages over the MH jacket. If your looking for more of a use all the time jacket / utility / not concerned with weight and how it packs as much - go with MH.
I have the Montbell Permafrost Down from...
I have the Montbell Permafrost Down from a few years back. Will the Frost Line sit closer to he body...less of the 'Michelin Man' effect?
I just picked up the Frost Line. Feels like a sleeping bag above your waist, the only problem is it looks like a sleeping bag above your waist. "Michelin Man" for sure. Perhaps a reasonable sacrifice for most to get this much warmth and versatility for the money.
Extremely warm, light, and supple. You can't buy a warmer jacket at this price point. This is not an expedition jacket, but it is much warmer than any other down jacket that is similarly priced. The baffled construction eliminates cold spots. The hood is great. The shell fabric is fairly sturdy, but for rough conditions I wear a tough gore-tex shell over it.
montbell: ruler of the down world
This jacket rocks. It is made of 30 denier so on the more durable side for montbell. The down is very lofty and soft. The jacket is fully baffled so very warm.
I wear a medium, I am 5'9", 155 pounds and the jacket layers well over an arc'teryx gamma mx and mountain hardwear alchemy. A large would have been to big.
I also own the Outdoor research megaplume (similar to the Mountain hardwear sub zero Sl), this jacket has maybe half an inch less of loft for alot less weight.
Out of the main brand companies, montbell is ruler-Western mountaineering, Feathered friends are Emperors. Buy montbell down, you will love it.
