Looking for a Christmas gift? PHaT, which stands for Protect your Head at All Times/Protect your Head on All Terrain, suggests a helmet. The group promotes helmet use at ski areas in Vermont. "Helmets are a good thing," said Robert Williams, M.D., doctor to the Smugglers Notch Ski Patrol and associate professor at the University of Vermont College of Medicine. "They're not a license to ride irresponsibly, but an extra measure of protection whose time has come," Williams continued. Williams said peer-reviewed studies – as opposed to less rigorous reports - show that helmets reduce the incidence and severity of injuries, do not increase the risk of neck injuries, and do not lead to riskier behavior.
