I'm 6'2" and weight 190 lbs.  I am constantly finding myself between sizes.  On most V-necks, Mossimo, Hurley, etc., I am a Large, so I got a Large in this shirt.  It is a good fit, but I will have to air dry it, no heat.  It cannot afford to be shrunk even a little bit.  If you are my height or taller, be sure to get the XL.
