I ordered this shirt to wear during outdoor activities, especially kayaking, to keep the sun off my skin. I absolutely love the shirt, and the print of the ivory color. Very lightweight, and should work well in hot PA summers. However, the medium, which is my tried and true EB size, is WAY small. I don't care about buttoning, as I'll wear a tank under it. The part that is the worst, is the arms/shoulders. I felt Chris Farley doing "fat guy in a little coat" - and I am not fat by any stretch. I don't know if maybe this particular shirt is size incorrectly or what. I'm considering sizing up to an XL to be sure I have plenty of freedom of movement in the shoulders for kayaking.
