These are padded and reinforced thigh armor used from the 12th up to the 15th century. This version is canvas, with a built-in kneepad. I lace on wingless aircraft aluminum cops for SCA combat. My cuisses are reinforced with 1-3 thicknesses of garden hose, keeping the weight and heat at a minimum and protection at a maximum. The shells were made by the same Knight as the arming coat I use.
