The Stilo Top Air System takes fresh air to the driver but also ventilates the drivers scalp. The helmet's inner liner design let's fresh air in through one set of holes and vents hot air out of a seperate set, creating an air flow ideal for the head cooling.
Top Air System can be fitted onto the ST4 F & FN and GT Wide models (The ST4 Wide version requires the helmet to be fitted with a long visor kit) |
