The ST4 is the first helmet in the world which has been homologated for use in F1 with integrated earmuffs. These earmuffs provide a significantly quieter environment for the driver by aurally isolating the ear. The pressure upon the head can be adjusted by replacing the special foam rubber pads placed between the earmuff and the helmet. The earmuff’s unique shape ensures they stay in place and do not make the helmet difficult to put on or take off.
The ST4F N comes with a 3mm clear visor for the absolute best in protection. For spares, you may choose from Clear, Yellow, Smoked and Irridium shields for driving in different lighting circumstances. All Visors mount with four specially machined aluminum fasteners and provide an air-tight seal with the rubber grommet on the 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 Composite Helmet is the same helmet shape as the ST4N Zero 8860 without the much more expensive carbon high-title shell and 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. The optional Aero kits will optimize airflow over the helmet for open cars. Also perfect for Karting
Features an M6 nut integrated into the shell for interfacing with Head and Neck Restraints.
