This set of articulated poleyn knee armor is constructed from 18 gauge steel plates. The armor for one knee is essentially five plates of steel fitted together with hinged rivets; they afford protection to not only the knee but the lower thighs and upper shins. The armor is well-articulated and does not greatly hinder movement.The armor is buckled to the legs with a set of three thick leather straps; it can be adjusted to size with the antiqued steel buckles.
