Full-Face Auto Racing Helmets
S10 = Snell SA2010 (Special Application) approved. The Snell Foundation SA2010 rating has been developed to provide the best safety protection for auto racing drivers who are restrained in their vehicles. An SA2010 rated helmet may not meet DOT specifications for street use, such as on motorcycles. As of January 1 2012, SCCA requires SA2005 or newer helmets.
