Husband loves it!
Color: Dark Gray, Size: Large
Husband loves it so much we purchased a few different colors. No shrinking while washing, true to the size and color, soft yet warm. Great price! For a guy who prefers only hoodies, he now chooses these shirts when we go out for dinner or an event.

Might be great, if the outdoor temperature drops
Looks nice and it fits. But giving you a review of what it feels like, you will have to wait till it gets below 65 degrees.
