Hey there playas! I bought two waddaplaya shirts for an upcoming golf trip to Scottsdale, AZ. These do run a size big, so if you wear an XL normally, like I do, go down to a Large. Matt suggested this, and he was exactly right. They fit like a baus! Very lightweight, very good cooling effect. PLUS, every one loved the designs. I got the star spangled polo, which looks great, and the green golf one ( I forget the name). Everyone commented on the green golf shirt. I'll definitely be adding a few more of these shirts to my wardrobe.
