Stilo: Stilo ST4F Composite 

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.

Stilo: ST4 GT W Composite 

This is a slightly heavier version of the ST4 GT W Carbon helmet. It is made from a Kevlar Multi-Sandwich Fiber composite formed in an autoclave.
It carries the same Snell 2010 certification as the Carbon helmet, but the different material adds the weight. This different material yields a slightly heavier
helmet, but at a reduced cost. The Snell 2010 rating satisfies almost all racing sanctioning bodies’ requirements for helmet certifications.

•The ST4 GT W is designed to satisfy those closed cockpit drivers who yearn for a larger eyeport. The cutout for the eyeport is taller than the standard
  Formula version and has a special visor to accommodate the larger opening.
•Available with integrated Electronics, Air Supply and Hydration or any combination of the three, 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 to interface with Head and Neck Restraint Systems.
