I'm on the taller side but also fairly slim and sometimes I order mediums in US products that end up being a bit big on me, but this medium fit just right. Only thing that threw me off a bit with this fleece was the zipper being on the left instead of the right, but the feel and the quality of the product are fantastic. Its super comfortable and its a great light weight jacket or thin layer for spring/fall/camping etc. My wife even loved it and was looking to buy one of the womens ones for herself.
