For the price, this shirt is a great value. The material is comfortable and seems like it should do a good job at breathing and keeping me cool. I'm 6' 2", about 165 lbs., and normally I get a medium-sized polo shirt because I don't like shirts to be really baggy. I don't like skin-tight either, but just close-cut but with room to move. Following the advice to order up a size, I bought this shirt in a Large and it's a great fit. Oh, I should also mention the shirt is soft and I don't really feel the seams while wearing it. (Some shirts like this have really scratchy seams... that is not the case here!)
