Stilo ST6 FN Zero Carbon Racing Helmet - FIA8860

Stilo ST6 FN Zero Carbon — FIA8860-2018 Racing Helmet

The ST6 FN Zero is Stilo's lightest open-wheel helmet — PURO-technology autoclave carbon (no clear coat), FIA 8860-2018, in the "Formula Naked" configuration with no electronics or side ports for maximum lightness and aero. Handmade in Italy, ~10% lighter and ~26% more airflow than the ST5 FN. The pure open-cockpit weapon, without the ballistic ABP weight.

WHAT'S INSIDE THE SHELL:

• PURO-technology carbon shell — high-tensile autoclave carbon, no clear coat; ~1310 g small shell. Handmade in Italy.
• FN "Formula Naked" design — no electronics or side ports; lightest and most aerodynamic Stilo for open cockpits.
• Three shell sizes — smallest, lightest shell per driver.
• Dual-locking visor — fully shut or vented; updated effortless pivot.
• Redesigned ventilation — six chin-bar vents plus crown vents; ~26% more airflow than the ST5.
• New wider eyeport — increased downward field of view for open-wheel.

FAQ

ST6 FN Zero vs ST6 FN Zero ABP?
Same shell; the ABP adds reinforced ballistic chin/forehead protection at a small weight penalty. If ABP isn't mandated for your series, the standard Zero is lighter and cheaper.

ST6 vs ST5?
The ST6 replaces the ST5 — ~10% lighter, ~26% more airflow, a wider eyeport, and an updated visor pivot.
