My husband loves his shirt. The material is incredible. He's naturally a sweatier guy, but stays cool in these shirts. We had to order online, so sizing was tricky. He's about 200bls, 6ft, and we did Large Athletic. His collar size is 17.5-18 and the collar is pretty tight. We ended up ordering a button extender for the top button. But the rest of the shirt fits so good. We will be purchasing again!
