Cuisses are a form of medieval armor worn to protect the thigh. The word is the plural of the French word cuisse meaning 'thigh'. While the skirt of a maille shirt or tassets of a cuirass could protect the upper legs from above, a thrust from below could avoid these defenses. Thus, cuisses were worn on the thighs to protect from such blows. Padded Cuisses made in a similar way to a Gambeson were commonly worn by knights in the 12th and 13th centuries, usually over Chausses and may have had Poleyns directly attached to them.
