FORMULA AIR FLOW

TOP AIR SYSTEM KIT
The exclusive Stilo “Top Air System” takes fresh air to the driver’s head and nose.
With the innovative system for the air flow regulation you can favor the air flow on the driver’s face for a better breathing or for cooling the driver’s head. The Top Air System can be fitted onto ST4 Formula and GT models.
Thanks to the fixation system you can fit it more than once replacing the dedicated fixation tape.
Available also without flow adjuster. (?)

SIDE AIR SYSTEM
The driver can breath fresh air when driving in close cockpit cars.
The air coupling for the helmet is made for tubes of a 20mm Ø.
Couplings are available for tubes with a different diameter, up to 32mm.

DRINKING SYSTEM
ST4 and ST5 are homologated with a drinking system integrated.

The drinking system is comprised of a tube going inside the helmet with a silicon bite valve with anti-backflow system and a male quick coupling. You can connect the drinking system to the hydration bag with the female coupling. The drink system can be connected to the hydration bag through the female coupling as shown in the image.

QUICK COUPLING
Quick coupling for drinking system with anti-backflow valve. The coupling assembly is designed to allow the driver
a quick evacuation. In case of emergency indeed, by just a slight tug, the coupling slips off releasing the driver.

REMOVABLE EARMUFFS
ST5 is homologated FIA 8860-2010 with integrated earmuffs that offer excellent insulation from external noise and are certified for use in racing. They are not fitted with speakers which are not permitted on track: communication is always carried out through earplugs (optional).
The pressure on the driver’s head can be adjusted with the special spare foam rubber paddings of various thicknesses to be positioned with velcro. Should you wish a lower sound insulation, earmuffs can be replaced with dedicated earcushions provided with the helmet.
