I was shocked at how warm it kept me in the snow today despite the coat itself feeling so light! This is perfect for winter over any outfit!FOR REFERENCEI ordered the "White 2" I'm 5'8" weigh 205lbs and round in the middle or apple shape.CONSTRUCTION - The shell is a very tightly woven water resistant matte finished nylon type fabric. It does make a bit of windbreaker type noise when moving around, and water just beads off of it, at least in a light rain, I haven't worn it in a heavy down pour yet. - The black liner goes into the sleeves not just the body, making it easy to slip over clothes. - The tag says it is filled with 230g of duck down. It's definitely filled well and poofy, and I cannot feel any feathers spines so I believe it's 100% down. - This particular model has actually 2 collars, the huge down filled outer collar which has elastic cinch strings to draw it in close to your neck. Then it has a shorter fiber filled inner collar. This isn't a coat you can flop back the collar when you need to cool off, instead you'll need to unzip and drop it off your shoulders. Keep this in mind if you get hot flashes. - this has double closure, a 2 pull zipper, so you can pull it open on the bottom making it more comfortable to sit down. Then a snap flap over the zipper. THE FIT - This has enough room for me to wear a t-shirt and thinner sweatshirt underneath without feeling tight. - The sleeves are actually long enough and only pull up 4" when I cross my arms, also it gets snug acrossmy back but not tight and constricting. These are looser sleeves and accommodate my bigger upper arms. - The arm pits aren't binding and are made with consideration for layering. - The length is a couple inches longer in the back, so no exposure when bending down, well at least for people shorter than I. I get about an 1" of exposure. The front hits me just below my hip bones. The bottom edge has an elastic draw cord to keep the wind from blowing up it.STORAGE AND POCKETS This model only has has the 2 front hand pockets. They allow your hands to be under the layer of down, but aren't very deep and don't have a closure. I can get my entire hands in them if I close my hand, I won't be toting my very large Samsung Galaxy note20 ultra in one. OVERALL THOUGHTS I'm pleased with it other than to shallow pockets. It fits nice feels good and is warm. FYI it has zero stain resistance, well at least not mustard, ask me how I know.Hopefully this was helpful, Thank you!It truly is one size fits all and I was very shocked. I'm a large woman with a larger chest and I typically wear a 3xl. This coat fits me and my 11 year old daughter that is a string bean. It is very comfortable and light weight. I got it for my daughter and she didn't wear it this winter because by the time it arrived she already had another winter coat she was wearing. I am not sure how warm it is because I only tried it on to see if it really was one size fits all. It is very nice, but seems kind of pricey. I will have to update this review after she wears it this coming winter to see how it holds up to Maine winters. We are rough on winter clothing and it seems like it won't hold up, which is a little disappointing for the price of it. I expected a higher quality material on the outside, and it doesn't seem like it is by the feel, it feels like it will rip easily.I wasn't sure how a one-size-fits-all sizing would work out in a winter jacket, but I am happy to share that it does for me. For reference, I'm 5'6, 125lbs.Yes, it's a casual over sized look, but not so large that it looks silly. It has a bungee style adjustable cord that allows me to sinch the bottom of the jacket for a more customizable fit while helping to keep in warmth on really cold days. I also like the layered styling of this jacket with its sewn in sweatshirt hood and zippered vest. The layered look adds style to the jacket and keeps it young and interesting. The sweatshirt material used is nice and thick. I'm a big fan of down insulation, and this jacket is both warm and lightweight. It doesn't feel bulky or restricting, and the cut allows for layering underneath. Whether worn open with the chest zippered or snapped up completely, it's a very stylish garment. Just a note: the zippers on both upper arms do open, but they are for decoration only. They don't open up to useable pockets.The only negative issue I think is worth mentioning is that the main metal zipper is a bit temperamental. The silver tone metal looks nice, but it's glitches at times and doesn't zip as smoothly as I'd like. I'm hoping that with continued use, this problem works itself out.All in all, this is a nice jacket that is not run of the mill style wise. It looks great with jeans, leggings, or workout clothes and definitely stands out as unique.I posted some photos to give you a closer look and sincerely hope that they, along with my experience, will help you out a bit with your choice. Thank you!
