The 509 Delta R3L is the perfect combination of modern styling combined with versatility. The helmet allows you to keep the electric shield on to ride in comfort or easily remove the shield and wear with your favorite pair of goggles. Comes with the Fidlock® easy-open magnetic strap clasp that allows for easy tightening and removal. For the snowmobile riders you can add the RCA Plug (sold separately) to hook up your electric shielded helmet to the sled and activate the heated shield.
