I have several of this shirt. My husband and I wear the same size, so we share them. The shirt quality and feel are very good. Color doesn't fade. Can't have too many of them.
First, I hate a turtleneck. My wife laughed when the package arrived and wondered why I bought it. It's not binding at the next, very soft, and wears nicely. One issue I have had with turtlenecks is that my beard/whiskers create pills and pulls on the collar. So far, so good!
