I am 5'0" 110lbs, and always wear an XS. I usually like my jackets fitted (I don't snowboard) so was reluctant to size up but based on the other reviews, I got an S - phew. Even so, I had to take out the elastic around the waist (snipped the inside and took out the three seams, tedious but worth it) and it feels so much better. Who needs it tight anyway when you have the snow skirt in there? I use this coat to wear to work in Boston when the wool coat won't cut it in sub-freezing temps. I don't know why they even bother calling this synthric down, it's not nearly as warm as down, and I wouldn't wear this below OF, but it's okay when it's about 20F. The black is my no means black, it's charcoal, but I still like. The length is right b/c I am short, but the sleeves are outrageously long and a bit of a nuisance b/c the jacket material and velcro on the cuffs are stiff. I hate the double zipper more than anything b/c it makes it too hard to zip up and the inner flap is stiff and also gets in the way (do people ever really make use of the double zip?) Anyway the coat still does the job, I like the hood and waterproofness, I think it's breathable but then again I'm just walking in the city, and I would recommend this only if you like the cropped bomber jacket look and/or have long amazon arms.
