Stilo ST5 GT Composite Helmet - SA2020

The Stilo ST5 GT Composite Helmet is a great helmet for racers who want a competitive edge.  This new helmet is Snell SA2020 and FIA 8859 certified.  The redesigned shell optimizes shell size, airflow, visibility and weight.  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.  Wiring is all positioned safely and conveniently behind the padding so as to be transparent to the user.  Earmuffs provide a significantly quieter environment for the driver by aurally isolating the ear.  EPS cheek pads provide the best in lateral crash safety, while retaining the functionality of the earmuffs to provide a comfortable aural environment for communication.

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.

This helmet is ready for integrated electronics, air supply, and hydration or any combination of the three.  Additional options can be added at any time, and all of the options integrate seamlessly with the new ST5.

Stilo has two separate shell sizes for this helmet. This results in a helmet that fits better and is lighter weight.  Instead of filling a very large shell with lots of padding for smaller sizes, Stilo helmets have one shell size for XS to Medium helmets, and a different shell size for Large through XL helmets.
