I bought the Royal Heather in the Big. It's 50/50 cotton and polyester. It was too big for me so I washed it in hot water and dried it on high heat. It didn't shrink much so I washed it again and dried it the same way. Didn't shrink. Since it's still too loose for me, I bought the same shirt from Medium. It fits well. I washed in cold water and tumble dried. Shirt shrunk, now too tight. Very frustrating. In the photos you can see the size difference between Large and Medium. There is approximately an inch of extra fabric on each side of the Large. I am very disappointed that I bought two shirts but I don't want to wear either one.
