* Increased helmet usage, however, has not reduced fatalities. Most helmets are not built to guard against impacts at speeds skiers and snowboarders easily reach.

While we promote helmet usage, the medical literature indicates that helmets have significant limitations when a skier or rider is involved in a serious accident and the increase in the use of helmets has not reduced the overall number of skiing fatalities. In fact, more than half of the people involved in fatal accidents last season were wearing helmets at the time of the incident.
