Great coat but not the one for me - Marmot Montreaux Coat - Women's

Me- 5'3.5", full C+ bust, 115 lbs, not very muscular at the moment.
XS fit perfectly. I can see what others have mentioned about the bust. I was able to put it on over a hoodie, but I can see how others might prefer a little extra room up top. Small would have likely been fine but not as form-fitted on me.
This is more 4.5 stars. I would have kept the coat if I did not already have an arsenal of winter coats. I was looking for a winter dog-walking bomb-proof coat, and I think my old MH ski coat beats this. That was the sole purpose for me.
If I actually went out in the winter (where people would see me), then this coat would be perfect. It is nice and a flattering fit. I love the hood, and it appears quite warm.
I want to address the supposed zipper issues, as I first thought NO WAY when I tried it. The zipper is fine. You just need to understand how to work it. I messed with it and finally understood after about 10 attempts.
Listen/feel for the zipper to click in, then use the very BOTTOM zipper to initiate the zip. You can then use the top one, and it works perfectly. I was never able to get it to zip up without this process.
The soft liner is very comfy, I love the length (just below my knees).

Cons-it didn't seem to be as warm my Goretex 850 fill MH ski coat, so I will continue to use that as my dog-waling coat. One thing was that I could feel cool air creeping in from the bottom (of course, as it doesn't have a powder skirt. Not intended for skiing :))
I would have preferred something around the wrists vs just open cuff. That is all. A great coat if I did not already have multiple coats. Again, I was looking for a dog-walking coat.
