Have checked and have no pants in the sizes you want, all the pants I have left are all Empire Ltd pants in red in sizes S, M and 2XL so cant help on this side.
This is not the pack in question, this is a picture I just got off the web, it is the same as this but its only a 3 pot unlike this 4 pot. It is size L/XL. Can get a proper picture tonight and apologies to the Mod team if this is not allowed.
