HJC bicycle helmets are designed and engineered by placing all of the density, placement, shape, and material at the optimum point through precise measurements to enable ultra-light weight.
SELFIT™ is a self-adjusting fitting system that is an upgraded technology in bicycle helmet fitting.
By adjusting the 5-point snap fit, the helmet is set to fit the user’s head circumference, and the helmet’s front and rear length is adjusted by itself to match the changing head circumference according to the movement of the neck and head according to the change in gaze. The SELIFT™ system with the above function automatically adjusts play and provides consistent fit and comfort to the head.
5 Step snap fit
The 5-step snap fit located on the left and right sides of the helmet helps in more precise size adjustment. After setting the size according to the head circumference by adjusting the 5-point snap fit, adjust the fitting of the helmet by yourself according to the changing head circumference.
Adjustable wide divider
The optimal angle prevents twisting of the chinstrap for a more comfortable fit.
Air channel system optimization
A certain amount of air passes through the front vents, circulates inside the helmet, and finally exits through the rear vents. Improves internal airflow to dissipate heat and lower the temperature inside the helmet.
HJC’s in-mold construction combines the helmet’s EPS layer with the outer polycarbonate shell for greater structural strength. This enhances the durability of the helmet and greatly contributes to the completeness of the product.
Wind tunnel test
HJC is one of very few companies , and the only one in the country , to have a state-of -the-art wind tunnel laboratory capable of testing aerodynamics , ventilation , noise and more . The HJC wind tunnel laboratory measures air force in various riding conditions to improve helmet performance .
