An armguard is a protective accessory worn on the forearm, commonly used in sports like archery and fencing. It helps shield the arm from injuries caused by equipment or impacts during play. Armguards are typically made from materials such as leather, plastic, or fabric, and they come in various sizes and designs to fit different athletes. In archery, an armguard prevents the bowstring from hitting the arm during a shot, which can cause discomfort or injury. In fencing, it protects the arm from the opponent's blade. Overall, armguards are essential for safety and performance in these activities.
