## Technical Specifications

## Helmetsan Verdict
6D ATB-2T — A competition-grade dirt helmet built to keep riders cool under physical exertion and shielded from roost and track debris.

### Verified Advantages
- Extra-wide eyeport with molded non-slip goggle strap stabilization channels
- Featherweight 1346g shell construction significantly minimizes neck fatigue during long rides
- Aerospace-grade 100% carbon fiber shell delivers elite kinetic energy dispersion at minimal weight
- Dual DOT & ECE 22.05 certified for verified road and highway safety

### Considerations
- High cockpit wind turbulence (~100 dB at 100 km/h); hearing protection / earplugs strongly advised
- Requires separate riding goggles; unsealed eyeport offers no protection against highway rain and cold
