The ST4 Formula Helmet is the same helmet shape as the ST4 Formula 8860 without the thicker, heavier carbon shell. It carries the Snell 2010 rating which satisfies almost all 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.

Available with integrated Electronics and your choice of Air Supply or Hydration, this helmet offers flexibility while maintaining a clean cabin. There are no wires or hoses hanging down below the helmet – everything integrates seamlessly with the shell of the helmet.

Features an M6 nut integrated into the shell for interfacing with Head and Neck Restraints.

Noise attenuating earmuffs

  • 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.
  • You may also use Ear bud style earphones with an optional adapter.

Visor Options

  • The ST4 comes with a 3mm clear visor for the absolute best in protection. Also available are 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.

FIA HANS Posts

Comes with an M6 nut integrated into helmet shell for interfacing with Head and Neck Restraints. Note, HANS users must purchase HANS Posts from Stilo to use with their HANS - standard HANS Posts will not fit the integrated anchor..

Integrated Radio Options

  • The integrated electronics jack is positioned far enough away from the HANS post anchor in order to make the use of the jack trouble free even when the HANS is worn.
  • The wiring is all positioned safely and conveniently behind the padding so as to be transparent to the user. There are no hanging wires in the helmet, everything stays put where it is supposed to be.

Optional Hydration System

  • The ST4 is the first helmet in the world with an available integrated drinking system. Its most significant feature is of course a safety-related one: in an emergency, the driver need not worry about being held up by the hydration system. With a small force, the coupling breaks, leaving the driver free to evacuate the car. For mid-race driver changes, depress the release lever and get out of the car, leaving the hydration system prepared for the next driver.
  • Includes a Silicone rubber hose with a bite valve to be positioned within easy reach, without interfering with the microphone or the optional Air Supply System.
  • There is an valve integrated into the quick coupling that prevents leakage upon disengagement keeping the cockpit dry and messes to a minimum.
  • Optional Hydration bag is available which can be positioned in a convenient and secure location.

Optional Air Supply System

  • Also available is the Air Supply System which provides a steady supply of fresh air to drivers of closed cockpit cars. Many different attachments are available, all of which are integrated into the helmet shell.
  • Can be used in conjunction with a communication system.

Two Shells

  • Stilo has two separate shell sizes for this helmet. This allows us to make a better-fitting helmet that is lighter weight. Instead of filling a very large shell with lots of padding for a size small, we have one shell size for extra small to medium, and one for large and extra large

The ST4 Formula Composite Helmet is exactly the same as the ST4 Formula Carbon, but has a slightly heavier Kevlar/Multi-Sandwich Fiber shell. It carries the same Snell 2010 certification as the Carbon helmet, but uses more material to gain the necessary strength to meet the requirements. This yields a slightly heavier helmet, but at a reduced cost.

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.

Available with integrated Electronics and your choice of Air Supply or Hydration, this helmet offers flexibility while maintaining a clean cabin. There are no wires or hoses hanging down below the helmet – everything integrates seamlessly with the shell of the helmet.
