This was a nice shirt, but I seem to be in between the large and medium. The medium was closer but just a little too tight on the chest and I ran the risk of being that guy, rocking the smedium to show off what little muscles he has. The large was better fit for the chest/shoulders but just too long, especially the sleeves, which ran to my elbows, which I don't like.
It was light and I liked the feel so much that I considered getting it tailored, but that seemed dumb for a $15 shirt.
