Cuirass
A cuirass (/kwɪˈræs, kjʊəˈræs/ kwih-RASS, kyuu-RASS; French: cuirasse; Latin: coriaceus) is a piece of armour that covers the torso, formed of one or more pieces of metal or other rigid material.
The term probably originates from the original material, leather, from the Old French word cuirace and the Latin word coriacea. The use of the term cuirass generally refers to both the breastplate and the backplate pieces; whereas a breastplate protects only the front, a cuirass protects both the front and the back of the wearer.
