The quality of the material is great. Exactly the weight I wanted. In terms of sizing, I like the fit to allow for maybe a sweater underneath, and usually get a Medium in outerwear. This medium was a tad small, definitely couldn't imagine wearing a sweater underneath, or even anything with long sleeves. The most disappointing part is the sleeves. They were at least 2 inches too short. Maybe a large would fit better, but the product isn't impressive enough to be worth possibly having to return again.
