Bought a Large pair of MMA gloves and they seem to be way too big for me, measured my knuckle width the way shown and it seems to be about 8.5cm, there's not much of a difference when I measure with my wraps on. The small size says 8.2cm-8.5 and the medium is 8.5-9.1, i'm looking for a reasonably tight fit as I couldn't grapple properly at all in the Large ones. Any help is much appreciated, will rep anyone who helps!
