Just got this shell in this past Friday, and immediately took it to the resort on Saturday and in the backcountry on Sunday. It did extremely well in powder - kept me dry and also was an awesome layer in blocking the crazy wind. I'm 5'3" and 125 lbs and ordered a medium. A small would have fit well, but the medium was perfect to layer over a puffy in the backcountry. Even without layers underneath, it has a good shape to it and doesn't look big or boxy. I am looking forward to wearing it a ton this winter and also this summer as a rain jacket.
Two thumbs up for this one, Mountain Standard!
