Gamboised cuisses were padded thigh defences, with the thickness and density of the aketon. They came down to below the knee, so needed to be made carefully to allow the knee to bend properly.
Gamboised cuisses were usually worn over rather than under the mail chausses by knights and men-at-arms. They often included a poleyn or knee-plate of hardened leather or iron. Sometimes they were also worn by themselves as the only form of thigh protection by infantrymen.
