Have a bunch of these now and love each one. I wear them for all sorts of things, from long runs to casual dinners out and occasionally to the office. The material is light weight and breathes nicely without getting soaked with sweat on a run, but heavy enough not to look like a see through t-shirt for other occasions. 6'2" about 195 and the large fits nicely. There long sleeve version is usually a little short in the sleeve for me but these short Ts are great.
