A baseball helmet is a protective headgear worn by players in the sport of baseball. It is designed to shield the head from potential injuries caused by fast-moving baseballs, especially during batting and base running. Helmets are typically made from lightweight materials like plastic or composite materials, ensuring comfort and safety. Most baseball helmets feature a hard outer shell and a padded interior for shock absorption. They come in various sizes and styles, often including a faceguard for additional protection. Wearing a helmet is mandatory in many leagues to promote player safety and reduce the risk of head injuries.
