The Schuberth SK1 Carbon helmet has a lightweight, hand laid carbon, and autoclave cured shell, derived from Schuberth's experience gained in Formula 1. Carbon helmet is finished in a matte clear coat, and includes top air scoops as standard. Optimum circulation is achieved through aerodynamic design and air flow channels built into the EPS, providing the ideal flow for intake of cool air and exhaust for hot air. Two-stage visor lock ensures the visor always closes symmetrically and therefore securely. Stage One lets in a small amount of air while the visor is still securely locked. Stage Two creates a firm visor seal that will keep out fine dust or water. Snell-FIA CMR-2016 homologated.
