Wind Tunnel Tested HJC helmets are tested both in the lab and in real conditions to meet the highest quality standards.HJC is one of the few helmet companies with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more.HJC´s wind tunnel test lab measures air forces under various riding conditions to improve helmet performance.Ventury Dynamics To achieve maximum ventilation, a technical adaptation of Bernoulli´s principle is applied to HJC´s aerodynamically enhanced models.In motion, the surface flow rate generally increases as it moves towards the rear of the helmet.Through pressure differences, cool air from the front intake is drawn through the rear vent to dissipate internal heat, providing the rider with optimal ventilation and perfect airflow while riding.In-mold Construction In-mold is a method that bonds the EPS with the outer polycarbonate shell for increased structural integrity.This enhances rider protection by providing a compact reinforcement and gives the product a perfect finish.Advanced Air Channel System A certain amount of air passes through the front air intake port, then circulates inside the helmet and finally exits through the exhaust port.Internal airflow is increased to cool the head and evacuate heat.Sizes - M:55-59 cm 21.6-23.2´´ - L:58-63 cm 22.6-24.8´´. tradeinn Bikeinn
