This is a great fitting rash guard for me. I am 5' 11" tall and weigh 194 lbs. I wear a size large. The sleeve length is correct also. It can be annoying if the sleeves are too long on a rash guard. The material is thicker that the Tatami Mike Fowler rash guard I also own. This gives me the impression that the Scramble rash guard will hold up longer, and resist stretching out after repeated washing.
