Men's small fits me perfectly (I'm 5' 4"). The material is extremely thin, but that makes it so light for the travel. If you hold the jacket in light, you could see through the fabric. I haven't tested water repellent capability yet. I'm a bit doubtful this will keep me dry but will update how it works. Many pockets are useful but since the fabric is so thin, there's a risk of making hole in the pocket so might need to be checked once in a while. There's a detachable key holder in the pocket. The color is absolutely charcoal/gray, which I think goes well with many different colors.
