Stilo Helmets ST5 FN ZERO 8860-2018 ABP Carbon Helmet
FIA 8860 certification valid through 2032 for these ST5 FN ZERO ABP carbon fiber helmets.
The Stilo Naked Helmet With Zero Compromises
The Stilo ST5 FN ZERO 8860-2018 ABP Carbon Fiber Helmet is built for professional racers who demand elite protection, extremely low weight, and a clean Formula Naked shell design. Designed for top-level open-wheel racing, the helmet meets FIA 8860-2018 ABP requirements with additional protection around the forehead and front chin bar areas.
The ZERO version sits at the top of Stilo’s lightweight ST5 lineup, using high-tensile carbon fiber construction to reduce driver fatigue while maintaining the protection required for professional competition.
Ultra-Light Carbon Construction for Serious Racers
The Stilo ST5 FN ZERO 8860-2018 ABP is designed for racing environments where every ounce matters. The FN, or Formula Naked, layout features a streamlined aerodynamic shell developed specifically for open-cockpit racing.
The helmet is also ready for non-integrated electronics, air supply, hydration systems, or a combination of the three, while removable cheek pads and top pads allow drivers to fine-tune the interior fit.
Advanced Ballistic Protection
The ABP, or Advanced Ballistic Protection, design adds increased protection to the forehead and front section of the helmet. This additional reinforcement requires a smaller visor opening compared with the standard ST5 helmet line.
Removable earmuff cushions help isolate the driver's ears from surrounding noise, while pre-installed HANS posts make the helmet ready for professional competition.
