The Stilo ST4F Carbon Formula helmet, designed for professional circuit use in Formula cars. Snell 2010 certified and since 2009 the ST4 is FIA 8860-2004 certified (specific homologation for Formula 1). The ST4F1 8860 helmet was tested by Sebastien Loeb during his test with Red Bull F1 where the excellent aerodynamic characteristics already shown during the development testing were confirmed. It's constructed from the very best materials, including carbon fibre and EPS expandable polystyrene, formed using an autoclave, to combine a very low weight helmet to achieve the highest safety standards.

This helmet is fitted with a radio system that includes a magnetic-dynamic noise cancelling microphone, integrated radio connection plug, ear plug connection and earmuffs. The helmet also features an integrated radio connection, so no more hanging cables and possible breakages. The whole electronics package, as well as the radio connection plug are integrated into the helmet. Additional wiring connections for the most common car radio systems are also available.
