Purpose-built for the street. A new benchmark in comfort, quiet, stability and ventilation. Arai applied the same tireless 24-7 focus devoted to their race helmets to designing it, refining and adapting proven concepts to a new purpose. On the long, narrow end of the head shape spectrum, the Signet series has always been the "go-to" helmet of choice. The new Signet-X exemplifies that shape in a feature rich package. The Signet-X has Arai's Long Oval (LO) interior fit shape. Longer front-to-back and a more narrow side-to-side (as compared to Intermediate Oval).
