Columbia almost never makes mistakes. I have a very old Columbia fleece vest that this one is replacing, and decided to go tall for the butt coverage. I'm 6' but not heavy or heavily muscled. The L/tall was a snug fit and its armholes were much smaller than my old vest, impinging on shirtsleeves. The XL/tall is perfect. If you don't want a snug fit, size up.
