A ski helmet is a helmet specifically designed and constructed for winter sports. Use was rare until about 2000, but by about 2010 the great majority of skiers and snowboarders in the US and Europe wear helmets.Helmets are available in many styles, and typically consist of a hard plastic/resin shell with inner padding. Modern ski helmets may include many additional features such as vents, earmuffs, headphones, goggle mounts, and camera mounts.
