Stilo AA0810AF1X59 FN Carbon Full-Face Racing Helmet Size - ST6 59 SA2025

The Stilo ST6 FN Carbon is the evolution of the legendary ST6 helmet platform, trusted by champions across the globe. Engineered for open-cockpit and open-wheel racing, this size 59 (Large) helmet combines Stilo's advanced Puro Technology carbon construction with a refined aerodynamic profile to deliver exceptional protection without unnecessary weight.

Formula Naked (FN) Design: The FN designation stands for Formula Naked, a configuration specifically engineered for open-wheel and open-cockpit racing environments. Unlike the GT variant, the FN eliminates integrated side ports, reducing weight and providing a cleaner aerodynamic profile while still maintaining compatibility with Stilo communication accessories.

Puro Technology Carbon Shell: Built using Stilo's proprietary Puro Technology, this helmet uses limited fillers, clearcoats, and lacquers — delivering an ultra-lightweight carbon shell without compromising structural integrity or finish quality. The ST6 FN Carbon is up to 10% lighter than its predecessor, the ST5 FN Carbon, with shell weights starting from just 1,180g on the small shell.

Key Features:

• Certifications: Snell SA2025 and FIA 8859-2024 homologated — meets the latest safety standards for auto racing
• 3 Shell Sizes, 8 Fit Sizes: Available in small, medium, and large shells spanning 8 head circumference sizes for an optimized, lightweight fit
• Improved Downward Visibility: Redesigned eyeport profile provides enhanced downward sightlines, critical for formula and open-wheel driving environments
• F1-Tested Aerodynamics: Refined front and top aerodynamic geometry delivers exceptional stability at high speeds with reduced lift and noise
• Redesigned Front Ventilation: New ventilation inlets maximize airflow and help prevent visor fogging without any compromise to structural safety
• Dual Locking Visor System: A new dual-position locking mechanism keeps the visor securely fixed in both the fully closed and vented positions
• Improved Interior Padding: Redesigned cheek and comfort padding offers a more precise fit and improved stability during long stints
• Pre-Threaded M6 Insert: Factory-installed M6 threaded insert for HANS device anchor attachment (HANS anchors not included)
• Electronics-Free: No integrated electronics or side ports — the lightest, simplest configuration in the ST6 range

The Stilo ST6 FN Carbon in size 59 is the premier choice for open-cockpit competitors who demand top-tier Snell SA2025 safety certification, minimized neck load, and F1-inspired aerodynamic performance in a full-face racing helmet.
