Giro helmets are developed using the Wind Tunnel ventilation system. This sophisticated 25-hole system allows for perfect cool air circulation around the rider's head. Innovated ventilation tunnels allow cold air to enter the front of the helmet , then circulate over the head, and residual hot air is fed through the rear openings. It is one of the most efficient cooling systems available.
The In-mold design combines a hard polycarbonate outer layer and a foam EPS pad to absorb shocks or shocks . In the field of ventilation holes and ribs there is special reinforcement, all while maintaining the minimum weight.
