sorry mate. the knee pads are gone now.turns out i dont know how to take measurements. Long story short, XL PE knee pads are too big for me. I'm thinking perhaps large or medium now.
Going to risk it and try out a medium first - I dont suppose you would please consider letting your knee pads go for £20 (based on the assumption that you do not want the hassle of a returns in case of wrong sizing)?
oh and is the NT still available....i'm currently setting aside some pennies for it.
the NT is still around though.
