A breastplate is a piece of armor that covers the front of the torso, providing protection to vital organs during combat. Traditionally made from materials like metal or leather, it was an essential part of a soldier's gear in various historical periods, including the Middle Ages and Ancient Rome. In modern times, breastplates are often used in sports, such as equestrian events, to protect riders during falls. They can also refer to protective gear in other activities, like paintball or military operations, where safeguarding the chest area is crucial for safety.
