Helmets
protective head gear en.wikipedia.org/wiki/Helmet
Helmets are worn by rock climbers, ice climbers, mountain bikers, road cyclists, kayakers, skydivers, paragliders, in-line skaters, motocross enthusiasts and motorcyclists, auto racers, equestrians, hockey players, construction and utility workers, skiers and snowboarders; by professionals and amateurs, kids and adults, men and women. Wearing protective headgear is a matter of choice.
"Helmets are a viable piece of equipment for skiers and snowboarders, just as they are for any sport or profession where one might encounter a bump on the head," states NSP's executive director, Stephen Over. "But the bottom line is it's a matter of personal choice whether to wear one, or not." There are a wide variety of helmets available. If you choose to wear a helmet, it is important that it fits properly, is comfortable, and offers the appropriate level of protection for the activity of choice.
As you make your decision, take a moment to notice how many experienced ski patrollers choose to wear a helmet.
