Two issues: (1) very tight around the chest and arms, although the waist and collar fit well. (2) easy to fold. I refused to wear them as I would look like a crumpled sack after two hours a day.
Pros
These shirts are amazing, I have all the colors. I'm 39. I'm 6 feet 1,152 pounds tall. I wear them every day literally everything I wear lol
Cons
Not true to size. I may never shop at Revain again. It sucks.
