    This goes in my pack almost every time I leave. Its great over just a t-shirt on cool evenings and works equally as well under a shell while skiing in the winter. Super light and compressible for synthetic insulation and doesn't feel stiff or restrictive. Awesome piece. I did have to size up - I'm 6'3 180 and went with a Large.

    Warm, Light, Trim Fit

      I love this jacket for its durable yet soft fabric, light weight, and heat trapping properties. It fits nicely as a midlayer or can pull duty as an alpine belay jacket. Beyond being warm, light, and comfy, the jacket also packs down to the size of a Nalgene in the included stuff sack. I'm 5'8", 135 and the small works really well.

      civilian/ military

        I was on a military field training exercise and it rained the entire weekend none stop. We had our mil standard Gortex jackets on but the water soaked right through on the first night. By the way, we slept on the ground with leaky poncho's and boots that we never got to change. 14 out of 46 came down with hypothermia that night. Not me though! This jacket keeps its insulating properties even when wet. so i stripped down and wore this in my wet sleep system and dried up in no time and had an extraordinary dry night. Most amazing jacket ever!!

        Just what you need

          This jacket is lightweight, compressible and warm for size. The hood adds warmth that is worth the extra weight. Compressed, it is smaller than a nalgene and nearly disappears in a pack. Layered underneath a shell it is almost perfect. Not for extreme temps, but I've been comfortable down to the teens while not very active as long as I'm wearing the correct layers. The fit is spot on for me. I'm 6'2" and 185 and the Large is just like it should be.

          Worth every penny

            Got it to walk with the dog in upstate NY, wore it over medium weight fleece in 12 degrees with wind gusts of 40 mph, and did not feel the weather! And this is without the shell, amazing! Weighs nothing, wind resistant, cut is a little smallish. I wear medium, ordered large, fit's well. You will not regret!

            Can't think of a better jacket

              Extremely lightweight, super warm!, packs down very small, sheds water... awesome!

              Insulated hoods are amazing. It's like a jacket, scarf, and hat but the sum is greater than the parts. This jacket packs down to a bit smaller than Nalgene size in it's stuff sack. I keep it in there while climbing a multi-pitch so that I have it when I'm sitting around. It keeps you dry AND warm in the rain (unlike down, which doesn't insulate when wet).

              There is a velcro tab on the top-back of the hood that allows you to pull the hood back a bit. This feature is very nice when biking because you can wear the hood without blocking your view of the road when crouched over.

              I was out around town wearing only a t-shirt and this jacket. Temp was ~20F and I was nice and warm. I highly recommend this jacket.

              Goes well with hot sauce

                This jacket lives in the top of my pack while ski touring, and I pull it out anytime I stop to wait for buddies, dig a pit, drink some coffee or make a burrito. It's pretty warm and crazy light.

                I'm 5'8 130 lbs and got a medium. This size is something of a miracle - it layers perfectly both underneath and on top of my hardshell, which is a size small. Don't ask me how it works, ask the clever folks who designed this jacket.

                Durability-wise, I've been impressed. Given its weight, this is obviously not a burly jacket, and you should take care moving through brush. That said, I've snagged it a hundred times and grimaced, thinking I'd have a torn jacket, but still haven't noticed any rips or tears.

                Buy this jacket but keep your eye on your sneaky roommates, 'cause they'll definitely try to steal it from you.

                Goes well with hot sauce

                Function is Beauty

                  The label of the jacket includes the phrase 'Function is Beauty,' and this jacket exemplifies that mentality.

                  FIT: I'm about 5'10", 140lbs and wear a size 36 suit jacket, sleeves about 33". The small fits me almost perfectly, both in the chest and almost in the sleeve length. I'd take another half inch in the sleeves; they're not too short, but it would be nice for when I'm reaching upwards.

                  CONSTRUCTION: Beautifully functional detailing. There is a thick nylon strip that runs the length of the zipper to keep you from accidentally catching material in the zipper. The triangle of elastic in the sleeves is just enough to to keep the jacket snug at the wrist. The hood tightens along the sides of your face and has a velcro tab at back to further adjust. Adjusting the sides of the hood it a bit finicky, so set it and leave it. There is Nothing extra on this jacket; that's what I love it, and that's why it is so light.

                  WARMTH: I tend to get cold easily, and I've been very impressed with this jacket. With the hood up, I am comfortable in the low 30s with the jacket over a medium sweater.

                  IN USE: I spent a week backpacking at the Grand Canyon in January with this jacket, and it was perfect. On the rim, the temperature was around 10 degrees in the morning; I had a mid-weight base layer, thin fleece pullover, this jacket, and a hard shell. It was a light-weight solution, layered easily, and breathed well. I was comfortable. In the Canyon, I often wore just this jacket over a base layer and light fleece-pullover in the upper 30s with a stiff wind and was comfortable. When I wasn't wearing the jacket, I put it in the included stuff sack. It's highly compressible.

                  A couple days ago I tossed it on to go outside; it was in the low 30s but to my surprise it was raining. The jacket has some sort of permanent water repellent built into the nylon, and it works very impressively; the water beaded and didn't even soak in when I pressed it against the coat.

                  This is a great jacket, and I look forward to many years of use out of it.

                  Function is Beauty

                  league of its own

                    This jacket is the first light synthetic jacket I've tried which comes even close to the warmth I feel when I put on my mountain hardwear sub-zero down. I have another synthetic insulation piece which is pretty disappointing after trying this one on. And yet somehow its more packable than a lot of the others. Anyways, SUPER impressed w. Montbell products.

                    Two thumbs in the air!

                      I bought this jacket after comparing it to the Mountain Hardwear Compressor PL hoody. The Montbell is more minimalist, it doesn't have a hood adjustment, napoleon pocket or quite as much fill as the compressor (about 3 ounces less fill). But I LOVE my montbell thermawrap. The fit is the best of any synthetic jacket I've tried on, I got an L and I'm 6' 185. I would really give two thumbs up on this jacket, it's built with a lot of quality for sure. Thus far it has been the perfect go to jacket for those cold drizzly pac nw days.

                      Amazingly warm and light

                        I was looking for a jacket good for 40-50 degrees w or w/o windy weather. This is perfect for my needs. Wore it in 48 degrees with 10-15 mph winds with a long sleeve tshirt underneath, and I was a little too warm. The jacket is very light, and durable with great wind protection. It runs small so, size up if you want extra room for layers.

                        MontBell Ultralight Thermawrap Insulation Parka

                          This is now my favorite jacket when the mercury starts to drop. In the Cascades the wet snow can make life miserable for down. I no longer have to worry. I put it to the test in 35 F, raining with wet snowflakes mixed in while snowshoeing and was truly impressed(younger brother left his shell at home so he wore mine). Light rain is shed pretty easy, but the wet snow started to soak in as it stuck. The moisture eventually made its way through the jacket in the shoulders, but this was after 5 hours of being out in these somewhat miserable conditions. I noticed my shoulders were damp, but never cold.
                          While I have only had this jacket for a year, I am amazed at the abuse it has withstood. I have had a few incidents where branches have snagged my arm and caught the fabric or brushed up against one too many rocks, yet the fabric has not shown any wear and tear.
                          A bonus is it is not too puffy, so when layering, you don't notice a lot of bulk. I had my girlfriend wear to watch a soccer game. At first she was doubtful that it would keep her warm, but afterwards she remarked at how warm it actually was.
                          The zippers can be a pain to find at first, but they are very clean and almost hidden to the untrained eye. My only complaint is there is no internal water bottle/long pocket like my MontBell Alpine Light Down Jacket has(two in that jacket).
                          MontBell keeps it nice and light, and the Exceloft insulation is perfect for the wet Cascades. From Rainier to the Alps to the streets of Seattle, when the temps drop and rain is a possibility, this jacket is the one I grab from the closet.

                          Can i borrow your walk in freezer to test my new jacket?

                            My favorite piece of gear from the moment i opened the package. Super light and comes with a stuff sack that allows it to pack down to about the size of a 1L water bottle.I'm 5 foot 8 and about 145 pounds and the medium fit me perfectly. I have been using this jacket as my go to insulating layer while studying abroad in Scandinavia and i have yet to be cold in it, but i'v only had it down around 35 degrees. In order to accurately picture the awesomeness of this jacket imagine the Patagonia nano puff had a child (who was also a jacket) with Mick Jagger, and then this child was lost in the arctic raised by polar bears who taught it to kill seals with its mind. This child, now a full grown man jacket moved down to Antarctica and started killing whales with Japanese whalers while battling angry hippies. Eventually this jacket decided to give up its life of mindless violence in order to seek redemption and keep hippies all over the world warm. And that jacket, my friends, is the mont bell thermawrap.

                            Update: I have now had this jacket down to negative 10 Fahrenheit. Still kept me warm but I was skiing and active the whole time.

                            insulates like magic, holds up well

                              Took this with me on a June trip to the Cascades, 12 days of hard use, with it on most of the time (including in the sleeping bag). It did the job of keeping me warm, and weighs practically nothing. I love that its thinner than your typical down jacket, so putting a rain/wind shell over this doesn't require upsizing your other gear. Starting to show some wear already on the cuff, but I totally expect that given the use.

                              Havn't tested < 30 degF but love fit thus far

                                I'm 5' 10" and thin, the jacket fits great in medium. The fit is great zipped up, I compared Mntn Hardware, North Face to this jacket and found the hood, pockets, and overall fit of this jacket to be the best of the three. I do wish it was not shiny at all, but I think that is the nature of the material unfortunately and I bought this jacket for its cold protection and price point. I have not yet tested it in <30deg weather in the Northern U.S. and so will come back with an update if able.

                                Easy livin with this jacket

                                  To be honest, I'm not an outdoors guy. I really wanted a extremely light, maximally functional jacket so I can work with changing conditions while traveling. This jacket really fits the bill. I'm 5'7 with a 37" chest and the small fits me well. Snug in the right places to keep heat in. Works great as layer.

                                  Hi, I am a 5'4 115 lb. female. Do you think the men's small would fit me okay? I like things on the looser side, but I don't want it to be so big that it compromises the functionality/warmth of the jacket.

                                  Hi I like the look of this Parka and...


                                  I like the look of this Parka and wanted to know if it will be warm enough with a mid-layer for evenings and generally around the village and on hikes in Aspen in December (sorry I am from a warm climate so it's a dumb question for those in the know).

                                  Looking for something stylish to wear around town but I can use it on a hike. I hate huge big bulky jackets.

                                  I like travelling light so multi purpose is what I am after (plus I will have my luggage full with my ski gear).

                                  I am 6"1 and 215 so I reckon the XL looks a go?

                                  Is the hood big enough to fit over a helmet?...

                                  Is the hood big enough to fit over a helmet? Does it run big or small...or true to size??

                                  Is this hood helmet compatible? And if not...

                                  Is this hood helmet compatible? And if not can you recommend a synthetic puffy that is, for alpine and big wall pursuits.

                                  Best Answer

                                  This is not helmet compatible, unless you have a smaller helmet with an up-sized parka. Now assuming that you're looking for the same type of puffy (synthetic insulation and highly compactible), I'd have to say go for the Arc'teryx Dually Belay Parka. It's pretty warm plus is tailored to have a helmet compatible hood. This jacket hits the compactible/compressible and synthetic insulation criteria as well.

                                  How does this compare to the Patagonia Nano Puff Pullover? The addition of a hood aside.

                                  Best Answer

                                  The most accurate comparison would be to the Nano Puff Hooded Jacket, but some of the stats are the same.

                                  Both Nanos feature a 15d shell and 60g of PrimaLoft insulation. The Hooded Jacket lists at 14oz.

                                  The mont-bell piece has a 15d shell and 80g of Exceloft insulation. It lists at 12.8 oz.

                                  Both hooded pieces have a full-zip front, elastic cuffs, zippered handwarmer pockets, and a drawcord hem. The mont-bell has an adjustable hood; the Patagonia piece has an elasticized hood.

                                  The Nano Puff Pullover gives up the full zipper, the hood, the drawcord waist, and the handwarmer pockets in exchange for coming in at 10.2 oz.

                                  If you are really looking to go lighter and don't need the hood, mont-bell has this in a jacket version as well, with 50g of insulation, non-zippered handwarmer pockets, and a full-length zipper. And only 8.8 ounces.

                                  All four are nice jackets; just depends on what you plan to use it for. Good luck, and I hope that helps.

                                  I knew it wasn't the greatest comparison, but I own the Nano Pullover for reference so I was hoping to get a better idea. While I do like the Nano Pullover I am looking for something possibly a little warmer as well as something with a hood/pockets. I think that this just might be what I am looking for then.

                                  Hey Matt,

                                  Ya, I have a Nano Puff, too, and your question is totally legit as is, I was just trying to provide as much info as I could. I will tell you that the Thermawrap Parka felt much warmer to me than my Nano Puff, and the 80g vs. 60g of insulation tends to support that.

                                  If you're not set on synthetic, give the mont-bell Ultralight Down Inner Parka a look as well. What an awesome piece that is, toasty warm, and only 9.0 ounces.

                                  Anyone got any comparison of this and other insulated jackets eg Montane Flux Jacket or TNF Redpoint Optimus Insulated Jacket (both of which are available in Scotland)? I've managed to get hold of a thermawrap parka here, and find it hard to believe it'll be as warm as it's competition which is twice the weight, though it is surprisingly warm.


                                  Best Answer

                                  There is more insulation in TNF Redpoint Optimus (100g Primaloft vs 80/60 on the Thermawrap) so it will be warmer. TNF Redpoint also has a stronger ripstop weave and is a looser cut than the Thermawrap (for the same size). I think the Redpoint is meant to be more of an outer layer, while the Thermawrap is a little more versatile as it can be used as an outer layer or as a layering piece.

                                  Compared to Arcteryx Dually Belay, which is warmer? What is comfort temperature range if available?

                                  The Arc'teryx Dually Belay Jacket is going to be significantly warmer than this, but also far heavier. The Arc has around 150g of insulation in the jacket and weighs 24 oz. It is supposed to be almost as weatherproof as a hardshell while remaining breathable and warm. The Montbell on the other hand is around 12oz with 80g of insulation. Both are warm, but the Arc'teryx will keep you toasty down to some gnarly low temperatures. Then again, the Montbell costs 2.5X less than the Arc, something to think about.

                                  Does the hood fit over a helmet?

                                  Does the hood fit over a helmet?

                                  That depends on your definitions of "fit" and "helmet." The hood is on the smaller side - which I like when wearing a hat.

                                  But, for example, I don't wear it over my Giro Omen because I can't zip the zipper up high enough. I do, however, wear it over my Petzl Meteor III. The zipper still won't go all the way up, but 95% of the way is good enough for me.
