Stilo ST4 Formula N Carbon Fiber Helmet

The Naked line of helmets (designated "N") takes the concept of lightness further by eliminating the integrated accessory ports on the side of the helmet. This gives absolutely the lightest Full-face Formula style helmet in the world.

The ST4F N Carbon Helmet is the same helmet shape as the ST4N Zero 8860 with a more cost effective Carbon shell and without the FIA 8860 homologation. It carries the Snell 2010 rating which satisfies almost all US Based racing sanctioning bodies requirements for helmet certifications.

The shape of the Formula is conducive to use in open and closed cockpit cars, with an optional Aero kit to optimize airflow over the helmet for open cars. Features an M6 nut integrated into the shell for interfacing with Head and Neck Restraints.

Features:

• Noise attenuating earmuffs
• 3mm Clear Visor included
• M6 nut integrated for HANS restraints
• FIA HANS Posts
• Optional hydration system
