The Stilo ST5 GT Composite Helmet is constructed with a lightweight Fiberglass/Kevlar shell for weight-savings at a more affordable price. Features a taller eyeport to allow for use in both closed and open cockpit racers. Side-mounted ports allow for the easy integration of intercoms, hydration systems, forced-air, or all 3! Includes ear cushions (in place of intercom accessories). Pre-threaded M6-Insert (Hans Anchors not included). Snell SA2020 and FIA 8859-2015 homologated.
Stilo helmets are usually smaller than Arai or Bell, therefore we recommend using the size chart to find your correct Stilo size.
