Shell is constructed of Carbon Aramidic Fiberglass and engineered in four sizes Shell shape is designed to maximize aerodynamic performance and to minimize the risk of impact energies being channeled to the collar bone while reducing interference with racing suits Integrated Ventilation System with five large front vents and two rear extractors hollowed in the shell which direct air to the rider's head New internal chin channels distribute the airflow evenly thru the entire visor surface The wind tunnel tested spoiler maximizes aerodynamic performance and stability during high speed riding New Corsa R interior construction is engineered to allow a stable, embracing, and pressure free fit DOT and ECE approved
