Great versatile piece of equipment
I've owned this jacket for over a year now and I feel comfortable enough to review it now. This thing rocks incredibly warm for such a lightweight jacket. It comes everwhere with me and I don't even feel it. It's not the most durable jacket ever, so if you have a heavy pack I'd use a softshell or fleece instead. But when you stop moving and the packs come off, this goes right on. It's pretty windproof and will shed a limited amount of water...don't drench it though. Great jacket!
The center front length is too short. It is suitable for climbing where it's nice to have the hem above the harness, but it is really too short for any other use on me. Rest of jacket fit great though. I wear a Medium and am 6'0" with a very average torso length.
I was planning on doing some hiking in...
I was planning on doing some hiking in Denali Alaska around early September. I was wondering if this would be the appropriate type of jacket to use? If not, do you have any other suggestions?
Hey Daniel, this will be plenty warm. Average temperatures ranged from 40-55F last year in September in Willow, AK which is just south of Denali. In higher altitudes I'm sure the the temperature has potential of getting a lot cooler, so it would be a good idea to bring a waterproof technical along in case the weather get's nasty.
Does What It Is Designed To Do
This is the best as far as uber light insulation goes. So by that I mean it is perfect for people who are so weak that they can't carry a peice that will actually keep them warm when it gets cold. This thing only weighs 8 ounces so don't expect more than 8 onces of performance, and by that I mean that this is not some magical insulation that insulates better than down without the puff or the weight. This thing insulates about as well as a wind resistant sweater, and that is exactly what is supposed to do, just don't get your hopes up thinking it is magical. By the way I do not suggest sizing up since the warmth will escape from the nonadjustable cuffs and waist, and keep in mind you will be told you look like a trashbag if you wear this around town with your friends. Despite the criticism I have owned this jacket in grey for three years now and still use it very often.
I only recommend this jacket if you can fully appreciate the beauty of a well-designed piece of outdoor gear. Ooohhh this jacket is GREAT!
I have had this jacket for almost two years now and I can comfortably say it's the best jacket I've ever owned, and probably the best piece of gear you can buy for the money. I have traveled to five different countries, been on countless rock climbs, bike rides, and trails with this thing and it never fails. I wear it four seasons and it never hurts to have this thing thrown in the bottom of your pack. I love it, and just ordered a new one finally! I will keep buying these jackets every year no doubt. The only problem maybe, is that you need to be a little bit careful with fires and thorns on hikes. The material is bomb-proof until a spark lands on it or a rose catches it. A little epoxy fixes those holes nicely though.
New Best Gear!
I just returned from a three day trip backpacking through Pt. Reyes National Seashore. I had the need to wear my new Mont-bell Thermawrap jacket every day on this trip. It has become my new favorite piece of gear. Even though it being one of the lightest pieces of gear I own it is very warm and wind resistant. Our campsites were right on the coastline with strong winds and cold nights. It was comforting to put on the thermawrap and snuggle my chin into the soft collar liner. I would recommend this jacket to anyone
Outlayer in mid 30's
Inner layer below that.
Looks a little edgy, and that is good IF you want to avoid the cookie cutter look that Patagonia is moving towards with their bulky styles.
This jacket does NOT have the techno arcteryx look.
69" tall. 41 inch chest. 30 'inch waist. 16 neck.
I wear a medium. Fits like the suits I bought in Hong Kong. Build is excellent. Chestnut color is really cool. Sets you apart, but not like an astronaut. You can wear it to work, or the coffee shop, or out on your adventures. I wanted dark navy but it was out of stock. Glad I got the brown.
This jacket is sort of shiny. Depends on the lighting. But it does not have the saran wrap look.
You will not wear this jacket to repair your car, or to a business meeting with a client. But for everything else it is wonderful.
This jacket, IF you are athletic build, IS the ultralight jacket to own.
The patagonia nan puff jacket is blocky just below the chest. Might as well try to carry a child with that thing or pack some very big heat, like a sawed off shotgun.
In the 30's I wear it with a thin smartwool underlayer. After a cold winter surf in Ventura it is easy to pull on and warms me up right away. Forget about putting anything heavy underneath it. This is either an outlayer on somewhat cold days, or a top layer in the mid 30's. It is windproof. I felt no leakage.
It is delicate, so be careful where you drag your elbows. I am 36" in the hips and this jacket hugs.
One more time. If you are a fit person, this jacket is THE ONE. As my mama said, clothes that FIT almost always look good.
For those who insist on zip pockets, there is no way you can put anything of any mass in the pockets of any ultralight jacket. It will feel like a brick in your back pocket.
Buy it, and if you do not like it, then I will buy a used medium from you. Make it dark navy.
Great Layering Tool
I bought this jacket as a lightweight alternative to my old fleece jacket and have been very happy with it. Compared to fleece, I like the Therma-wrap for 3 reasons: it is much lighter, it is much more compact-able, and it blocks wind. Warmth wise, I have found my Therma-wrap jacket is roughly equivalent to my mid weight fleece jacket. The jacket is great for 3 seasons of warmth in the Pacific Northwest, and is perfect as a back up layer to toss in my pack for a weekend outing. I was afraid that the light weight material of the jacket would tear easily, however I have had no issues so far using the jacket for a variety of different outdoor and daily activities. I'm 6'2" and 175 lbs and the large fits me well.
What is the difference between this and...
What is the difference between this and the BC version. Was thinking of using this under a shell for lift a served cold days
The UL Thermawrap Jacket has 50g/m2 Exceloft insulation and comes in at 8.8 oz. for a Medium. The UL Thermawrap Parka has 80g/m2 Exceloft insulation and comes in at 12.8 oz. for a Medium. Both feature 15-denier nylon shells.
The BC only comes in a jacket, has 80g/m2 Exceloft insulation in the core of the jacket and 50g/m2 in the sleeves. Weight on the BC is 12.8 oz. for a Medium. The BC has a 12-denier nylon shell, fleece side gussets, and a slimmer cut.
I bought this jacket about a month ago before the snow fell here in MI and quickly fell in love with it! I needed a coat for bumming around town etc so the super specific mountaineering reviews didnt really apply and left me guessing. Bottom line - this coat is very light weight, athletically cut, and very well made. I tried on a TNF redpoint with similar insulation amount and left TNF store disappointed in the clunky feeling and very heavy jacket. So I figured Id blindly(couldnt find one in a store) try my luck with the montbell.
The first thing you will notice is how light this jacket is. Then you might wonder why you paid so much for so little (8ozs!!!!)? But dont worry it all works out. While the jacket is a little brisk in the wind while not moving, it is sufficiently warm when you're actually walking around(wearing at least one long sleeve top under it). Im usually quite cold-natured so I was surprised that this coat with a nike hoodie has kept me pretty warm in 20 degree temps. So this probably isnt your super cold go-to jacket but it seems versatile enough to wear from Fall through Winter and Spring.
The athletic cut on this coat will also be a nice surprise for athletic builds. Im 160 and 5'11", and the medium fits perfectly - sleeve length, waist and shoulders too! Instead of draw cords montbell uses elastic fabric wedges that actually work great and keep the cuffs and waist close to your body without having cords and velcro crap all over. Im also a huge fan of ballistic nylon so the fabric was a definite plus(also gives the lightweight properties not seen TNF redpoint). The brown color isnt too shiny either and looks really nice. So far friends and family have all commented on the jacket looking and fitting great. Overall the design is very sleek and minimalist in the best ways, you can tell it has incorporated the Japanese design elements hinted to on the Montbell site.
Bottom Line: Im very happy with the coat. Super light weight, reasonably warm, solid construction and aesthetics. Only negative is the price but this is well worth your pennies. Your buying quality here! One last ego booster is that nobody is wearing this brand and its not a played out yuppy soccer mom TNF jacket.
it`s lightweight - and therefore perfect for an jacket you want under your hardshell!!
Is the jacket as shiny as it appears to...
Is the jacket as shiny as it appears to be? I like everything I've read but I don't want a real shiny look.
Yes, it is. Check out the pic Barry posted above; that's pretty accurate. I bought one, but sent it back (but not because it was too shiny).
why send it back cameron?
18s4094932: I sent it back because both the mont-bell Ex Light Down Jacket and the Ultralight Down Inner Jacket are warmer and lighter, and the Alpine Light Down Jacket is a few ounces heavier, but significantly warmer. It just didn't have a place in my lineup, as those were better options for me. Keep in mind that I'm a gram-counting lightweight backpacker who spends most of his time in the Eastern Sierra (typically cold and dry), so my perspective comes from that; I was looking for a backpacking jacket. I ultimately settled on the mont-bell Ultralight Down Inner Parka for colder trips, and a mont-bell Ex Light Down Vest as a SUL option when conditions permit.
All three of the jackets I mentioned are down, however, so if you are looking for synthetic, and/or weight isn't a huge issue for you, this might meet your needs. I am a huge mont-bell fan, so I'm not dissing this jacket; I just found something that better suited my particular needs.
Another sizing question. Does this have a...
Another sizing question. Does this have a more athletic cut than a Patagonia nano puff? Nano puff seemed pretty boxy on me, even though I'm pretty boxy at 5'6" 160 with broad shoulders (40 sportcoat). Looking for a snug fit. M or S?
Yeah dude, this fits nothing like the Nano Puff. It's both longer and trimmer fitting, a true "slim" fit.
I'm primarily using this jacket to walk...
I'm primarily using this jacket to walk around NYC and to go on some hikes upstate. I'm thinking about the bulkier Patagonia and north face models but like the compressibility factor. Would this jacket keep me warm walking around with a t shirt underneath?
also 6'3 203 lbs, xl ok? and does anyone know anything about First Ascent gear?
Crazy light, super compressible; you can't get a better ultralight insulation layer. This and my Norrona paclite shell give me insulation and weather protection in less than 19oz, and in about 1L of volume. My next jacket will be the hooded version, gives a bit heavier insulation and a hood for only 4oz more. It's like magic, I just don't know how they can make such and awesome jacket.
Normal fit; I'm 5'8" 130lbs w/ a 35" chest and the small is great.
Buy it. You won't be disappointed.
I've been wanting this jacket for a while now and finally bought it. I think I will use it most as an A to B jacket in the winter and as a safety layer while touring. It fits great...not to bulky not to tight. I have the medium (5'11/155lb) Layers great under Arcteryx pac-lite and other jackets of similar fit.
Another Satisfied Owner
Add this to your must-have ultralight loadout. Stuffs tiny, super warm, quality construction. Everyone agrees, this jacket is the $h*t.
best purchase of 2009
The MontBell Ultralight Thermawrap Insulation Jacket was by far the best piece of gear I bought in 2009. I've always bounced around a bit with my layering/insulation set up but now that I have this jacket, my system is complete. It is durable, comfortable, lightweight, and of course warm as can be. I use this thing everywhere from summer camping trips in the alpine, to frigid winter days in the backcountry. The beautiful thing about it is that it's so light and packable I can keep it with me at all times. You never know what the mountains will throw at you.
My New JAcket
The performance, the fit, the quality and the feel are right here in this jacket. I really like it. Plus it stuffs down to nothing and is so light I keep it in the pack all the time.
