If you don't mind waiting for a custom made suit, I highly recommend these guys:
http://www.batesleathers.com/race_suits/onepiece.php
didn't even know Bates was still around. Bates,Vanson,, bullet proof old school,, heavy,heavy suits. The armour in the Bates is not as good as the Vanson [Just working on a Vanson] But personally I would put aftermarket armour in any suit. Vanson/Bates will last you a long time and take some real abuse,,, fit is not as good as the leather is thicker, but the fit is appropriate for the type of leather. "If" "I" was buying a custom suit I would go Pilot,Vanson,Bates,, and please,, go to a good tailor, flip the guy what ever he wants to measure you. Don't get your significant other to measure you,,PLEASE! Why is it people think leather lasts for ever! Get a new suit and save your butt. Five years is a long time now days!
