don't go by their chart..you will end up with one that is too big. when i did it said XL. way too big. traded back for L. perfect (6' 185lb, wear over rukka winter and summer jackets on street and leather suit with "hump" on track).
many moto shops and bike dealers carry them. find local supplier and try them on if you are uncertain on sizing.
one of the drawbacks of living in the sticks...not many dealers of anything...but the advice here sounds good- thanks. I will also be sure to purchase from an easy return vendor.
