Stilo AA0810AF2X540101 ST6 FN Composite White Racing Helmet Size 54 SA2025

The Stilo ST6 FN Composite helmet in White is the evolution of the legendary ST6 — a helmet trusted by champions across the globe. Handcrafted in Italy and certified to both Snell SA2025 and FIA 8859-2024 standards, this size 54 open-wheel racing helmet represents the cutting edge of composite helmet technology for open-cockpit motorsport.

The FN (Formula Naked) designation indicates a non-integrated sideport design, making it ideal for open-wheel and formula car drivers as well as sportscar competitors who prefer external communication and accessory integration. The autoclave-cured composite shell is produced using a newly developed manufacturing process unique to Stilo, delivering an exceptionally lightweight yet high-strength structure engineered to reduce driver fatigue during prolonged events.
