Not as tight as people commented about. I am 6'1, 210lbs and wear L in all other OR shirts. I ordered a XL bc of several comments in regards to "tight on the shoulders" and "order a size bigger". I definitely could have ordered a L. Shirt will now be used as more of a second layer and will be worn unbuttoned over another long sleeve. Still a nice shirt that is well constructed and what you would expect from OR.
