ST5F Carbon SA2015


The Formula line of helmets (designated "F") 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 cutout for the eyeport on all ST5 helmets is taller than the previous ST4 and has a special visor to accommodate the larger opening.

The ST5F Carbon Helmet is an evolution from the ST4 FN. It carries the Snell 2015 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.

  • What's Included

    • Helmet
    • Comfort Cushions
    • M6 Nut pre-installed
    • 1 Clear visor

    Optional Noise attenuating 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.
    • Also available with comfort noise reduction pillows

    Visor Options

      The ST5 FN Carbon 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.
