Alpinestars Missile Tech Mountain Bike Helmet

Lightweight and strong, the Missile Tech helmet has been designed specifically for downhill riding. Featuring 22 openings for maximum airflow and ventilation, the Missile Tech helmet is equipped with Mips® safety system How does the Mips® safety system work? The brain is typically more sensitive to rotational motion than linear motion because it has shear properties similar to water or gel. When different parts of the brain move relative to each other because of rotational motion, the tissues can stretch, which can cause concussions or other brain injuries. Rotational motion is a common cause of concussions and more severe brain injury in oblique hits to the head. The Mips® safety system consists of a low friction layer mounted inside the helmet. In a crash, the low friction layer is designed to move slightly inside the helmet to help redirect forces away from the head. This is intended to help reduce the risk of brain injury. . Other design features include Emergency Release System (ERS) padding for quick and safe extraction in the event of an emergency, the patented visor release system, a removable air vent on the chin for enhanced airflow and easy cleaning, hydration kit compatibility, a D ring closure for security and a removable and washable anti-bacterial lining with polygene, which is integrated into the fabric to combat odors.
