A ski helmet is a protective headgear designed for skiers and snowboarders. It helps reduce the risk of head injuries during falls or collisions on the slopes. Most ski helmets are made from lightweight materials and feature a hard outer shell with an inner foam lining for shock absorption. They often come with adjustable vents for temperature control and can be fitted with audio systems or visors. Wearing a ski helmet is recommended for all levels of skiers, from beginners to professionals. Many ski resorts, such as those in the Rocky Mountains or Alps, encourage helmet use to enhance safety. Additionally, ski helmets are often tested for safety standards to ensure they provide adequate protection.
