Sizing is worrying me. I wear a xxl in most gloves, Joe Rocket, AlpineStars, Warm and Safe. If I measure my dominant hand using a cloth tape measure following your diagram I measure just a hair less than 10" so a size large. I have never fit in a size large. I am in for a pair,at least, of Formulas. You think a large will fit me? I'll order large as long as I can exchange them for another size if they don't fit.
