The second coming of the Domain helmet features everything the original Domain has to offer--a light weight composite shell, multiple ram air ducts, fully removable comfort interior, and a fog free quick change shield--but goes one step further by including our new Proshield sytem. With a shield lock and sideplates, the Proshield is ready to keep you locked down and looking good.
