I'd get the same size if I were you, and you can always use a belt to tighten them up. From my experience being over 6', there's no way M will fit...ever, or even L with china sizes, unless you're into those tight short ankle pants. ;p
Just like horto, the quality of the pants really surprised me and they're affordable, light weight, comfortable, they also ventilate well and they're not baggy and low hanging in the crotch area so I cant see them ever tearing, and the knee pads are great!
