I wear really almost entirely south, but had here ordered M, because I wanted to have too large than small prefer. The result was that it fits perfectly. So prefer to order one size larger.
The material is relatively light and thin, but super warm and comfortable. Even after washing. The zipper is of high quality, as well as the rest.
A previous speaker the "crumpled collar" faulted. Funnily enough, he looks at me exactly the same as on the product image from, but that does not bother me much.
Am fully satisfied.
