It is a great coat and looks a lot better than it does on the model! It is unlined and very packable. I live in San Francisco and have worn it every day since I received it. The weather has been cold and rainy, and with a light sweater underneath, I have been comfortable. I am 5'3 and weigh 120lbs and the small fits perfectly. I struggle just a little with the zipper, but don't think it will catch on the material. Because of the snug fit I recommend ordering two different sizes to start with, just to be sure you aren't disappointed.
