I love this jacket, but it runs very large. I usually wear a large simply for the fact that my arms as so long, but this jackets was twice the size of any other jacket I own. I could literally fit two of me in it comfortably. The large was made for a larger grown man, not a woman. It was about the size of XXL. I sent it back for a medium which fits MUCH better. The arms are a little short, but that's my usual problem. Other than being way too big, I love this jacket now that I have a size that fits! Its super cute and does a fairly decent job of keeping the wind off of you. Not the warmest soft shell I own, but probably my favorite design.
