Familiarity: I returned this product before using it
I'm 6'0", 210 and size large fits me pretty well 99% of the time. This vest has elastic that fits very tight around the arm sockets (and I do not have big arms by any means). This was uncomfortable and caused the jacket to scrunch up and fit tight aroud my chest. Too bad because it's a really nice vest. Maybe if you're in the 190lb range with sort of skinny arms this could be great for you.
