I purchased one to try out as a work shirt. Liked it so much I purchased four more. They're light weight and breathable, but not too thin. I'm 6 ft and 170 lbs average/athletic build, and the medium fits perfectly. I would prefer the medium to be 1-2 inches longer at the bottom, but these are still great. Will continue purchasing these in the future.
