Stilo AA0810AF2X54 FN Composite Full-Face Racing Helmet Size - ST6 SA2025 54

The Stilo ST6 FN Composite is a next-generation full-face racing helmet engineered for open-wheel and open-cockpit competition. Built to meet both Snell SA2025 and FIA 8859-2024 homologation standards, it represents a significant evolution over the legendary ST5 platform. This listing is for the size 54 (XS) in the silver/titanium finish.

The "FN" designation stands for Formula Naked — a configuration specifically engineered for open-wheel cars and open-cockpit sportscar drivers who do not require integrated sideports. The design is optimized for aerodynamic performance and enhanced forward and downward visibility, which are critical attributes for formula and single-seater racers.

The shell is constructed using Stilo's proprietary ZERO Technology autoclave-cured composite layup process — a pre-impregnated composite manufacturing method that delivers an exceptionally strong yet lightweight shell. This production advancement achieves an approximately 11% weight reduction compared to the predecessor ST5 while also improving impact absorption performance.
