When I initially put this on I thought there was no way it would be thick enough to keep me warm. After having about a month I can say it's the perfect casual jacket for the Pacific Northwest. It is great in the 30-50 degree range, it helps block wind and rain but is not completely wind or waterproof. Only negative is the size. I am an athletic size 6 with broader shoulders. I ordered a Medium since it was a trim fit. The shoulders are a little tight with layers while the rest of the jacket is baggy. It does stretch and is fine if I am wearing a single top, so it wasn't enough of an issue for me to return it. Overall am very happy with the jacket.
