The mission is clear: keep on riding, with a safe head! Classic style meets maximum protection. With this helmet you are ready for a long winter. Aerocore construction with Koroyd ​ Smith's aim with the Aerocore construction is to increase airflow, improve temperature regulation resulting in fog-free vision and improve impact resistance. This aim has been reached through the combination of materials such as EPS and Koroyd , a revolutionary new material that absorbs more energy upon impact when compared to international standards, while increasing airflow. Aerocore construction through the use of Koroyd and EPS allows for more vents to be placed throughout the helmet without sacrificing protection and comfort.
