Classic style meets maximum protection. The brand new Mission brings the tried and trusted Smith fit along with thought out features, such as an adjustable climate control, Dial Fit-System and Snapfit-SL-ear pads. 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.
