To narrow around the shoulders. Fabric is nice however. Unfortunately had to send it back.

The fabric is very easy to get a snag. I got a snag on my first day of wearing it. I found out there is even a snag on one of the back-view display photos. I should have checked those photos more thoroughly when purchasing. However, I believe a snagging issue is unacceptable on a "golf shirt". It should be anti-snagging, otherwise, you can easily get a snag from a tree/a bush.
