Stilo AA0810AF2X550101 ST6 FN Composite White Racing Helmet Size 55 SA2025

The Stilo ST6 FN Composite is the evolution of the legendary ST6 helmet platform, handcrafted in Italy and trusted by champions across the globe. This size 55 White version carries full Snell SA2025 and FIA 8859-2024 homologation, making it race-legal for the most demanding sanctioning bodies worldwide.

The FN (Formula Naked) designation means this helmet is purpose-built for open-cockpit and open-wheel environments, featuring no integrated electronics or side ports to keep weight to an absolute minimum. The result is one of the lightest composite racing helmets available, up to 11% lighter than its ST5 FN predecessor, with small-shell weights starting at just 1,370g (approximately 3.0 lbs).

Stilo's proprietary Puro Tech manufacturing process — an autoclave-cured, pre-impregnated composite construction — eliminates the need for extra lacquers and coatings, delivering an exceptionally strong shell without unnecessary weight. The helmet is offered in 3 shell sizes across 8 head sizes to ensure the smallest and lightest possible shell for each driver's head shape.

Key Features:

• Snell SA2025 / FIA 8859-2024 certified — meets the latest international motorsport safety standards
• Handmade in Italy — autoclave-cured composite shell for exceptional strength-to-weight ratio
• F1-tested aerodynamics — developed with Formula One team input for a stable, drag-reducing profile at any speed
• Improved downward visibility — redesigned forward-projecting eyeport profile increases the driver's field of view toward mirrors, dash, and track
• Redesigned front ventilation — increased airflow through updated intake vents and internal air channels without compromising structural safety
• Top ventilation — ventilation holes channel through the EPS foam to reduce heat and moisture buildup
• Dual-lock visor system — secures the visor in both the fully closed and vented positions, compliant with FIA standards
• New injection-molded visor — coated with a high-performance washable anti-fog treatment for clear vision in all conditions
• Redesigned interior padding — improved cheek pads engineered for stability in open-cockpit environments with rear channels for easy installation of electronics, air, and drink systems
• Pre-threaded M6 inserts — ready for HANS device anchors (anchors not included)
• FN (Formula Naked) design — no integrated sideports, maximizing situational awareness and airflow

The Stilo ST6 FN Composite in White is the go-to choice for formula, sprint, and open-wheel racers who demand cutting-edge protection, minimal weight, and maximum cockpit awareness. Available in size 55 (Small shell).
