My son is 6'1" and with a large girth. He wears a XX or XXX in all his gear. Unfortunately these overalls were tight through the rear end and could not be zipped up over the tummy area. No Way! The length was fine and the quality is great. They fit my usually XL husband much better (a little long) so plan on purchasing them 2 sizes larger than your usual size. Again, these are great quality pants but the sizing is way off.
