Caveat: haven't worn it in the rain yet, so I'm reviewing for fit, style, comfort, etc.I'm 5'4", 150#, with an hourglass shape (busty 36 DD, and I'd my consider waist, hips and butt about average for my height, weight and body type.) I purchased a size large and it fits me like a glove, although I was able to easily layer it over a lightweight, slim-fitting knit workout jacket. It's very flattering for a curvy shape, although if I was any bustier it would be too tight in the chest. There is plenty of room in the hip area so don't be scared of it if you have been blessed more in the booty than I have. It is slim fitting through the waist, but not too tight for me--and I do NOT have a tiny waist by any means--but I can see how it probably wouldn't be the best fit for more of an apple body type. The taped seams do make the zipper a little finicky but I'll get used to that. It is as light as air, has nice zip pockets, and an adjustable hood (I had to search for how to adjust it - it's in the back of the hood). I like the longer length, that is what I was looking for. This is going to be wonderful for travel--it will compress into nothing--and very comfortable for everyday use as a windbreaker as well. It's attractive in an outdoorsy way but also manages to have a little style, and doesn't just look like hiking wear. I love it.
