This is one of my favorite shirts I own. I wear it to go out and I even wear it sometimes when at the gym. It's very breathable and even more comfortable. I will be buying one in every color. I usually wear a large in my clothes but got a medium and it fits perfect.
Rated 1 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is Fits Great and 2 is Runs Large
