Construction Hybrid shell construction Aerocore construction featuring Koroyd®: Smith's objective and design philosophy behind Aerocore™ construction is to increase airflow, improve temperature regulation resulting in fog-free vision and improve impact resistance. The objective was achieved 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.
