I'm 6'4", 240lbs with an athletic build.  I like closer fitting clothes, but these shirts are skin tight on me. They're also too short. I usually wear an XL, but this brand is certainly made for guys smaller than me.  With that said, they are perfect for guys looking for a vintage style v neck tee with the classic thin cotton material. Proceed with caution if you have a bigger build, unless you just really like showing off.
