A cuirass is a piece of armor that covers the torso, typically made of metal or leather. It is designed to protect vital organs during combat. Cuirasses were commonly used by soldiers and knights in various historical periods, especially during the Middle Ages and the Renaissance. Cuirasses can be found in different styles, including the breastplate and backplate, which are worn together. They were often part of a larger suit of armor, providing both protection and a degree of mobility. The design and materials of cuirasses evolved over time, reflecting advancements in warfare and technology.
