I wear a regular size Large, not fitted. These shirts fit way to snug. The neck fit correctly but not in the chest. Also, the one shirt I tried on had a flaw in the material - about a 3/8" diameter patch of white thread in the weave of the gray material, right in the middle of the shirt. I purchased one gray and blue package. The gray was a nice medium shade of gray, the blue was dark navy. The price of the shirts was too good to be true. Can't recommend. I'm returning them.
