Spaulders
Spaulders are pieces of armour in a harness of plate armour. Typically, they are a single plate of steel or iron covering the shoulder with bands ( lames) joined by straps of leather or rivets. By the 1450s, however, they were often attached to the upper cannon or rerebrace, a feature that continued into the 16th century.
