Tassets are a piece of plate armour designed to protect the upper legs. They take the form of separate plates hanging from the breastplate or faulds. They may be made from a single piece or segmented. The segmented style of tassets connected by sliding rivets produced during the 16th century is also known as almain rivets. The Japanese (samurai) form of the tasset is called kusazuri, the kusazuri are attached to the bottom edge of the samurai chest armour (Dou or dō).
