The 4Forty Air helmet also protects the back of the head in the event of a fall. The light construction and ventilation holes ensure sufficient airflow. The adjustable tightening strap allows you to adjust the size to fit your head perfectly. MIPS technology is integrated into the tightening collar. Antibacterial Ionic+ pads. Fidlock magnetic buckle that you open and close the gloves with one hand in just a second. The 3-stage visor enables an even better fit with the cycling glasses.
MIPS uses a slip-plane system that moves inside the helmet, mimicking the brain’s own protection system. This layer is designed to rotate inside the helmet with the intent to potentially slow or reduce the amount of energy transferred to or from the head. Science tells us that if we can reduce the strains associated with rotational acceleration, we might reduce the risk and severity of brain injury.
