Stilo ST5 GT carbon helmets are redesigned shells that optimize shell size, airflow, visibility, and weight, which means you get a better fit with more visibility in a comfortable-to-wear helmet. Plus, the carbon helmets are 50/60g lighter thanks to Stilo's Puro Super Smooth technology-a superior finish that removes the need for lacquer, and also saves weight. Stilo ST5 GT carbon helmets are available in a range of sizes, and all are Snell SA2020 and FIA 8859 certified.
