I always wear medium shirts. I'm 5'10" and 160 lbs. I'm athletic build and initially ordered medium. I had to send back the mediums as they fit like little girls shirts. I bought the large and they fit perfectly, like all other medium sized shirts I wear. Good shirts! Just order one size up. The description says to order one size up, but I skipped that because I rarely read clothing details, especially t-shirts.
