Teijin Co., Ltd. "UV & IR Cut Shield" uses heat ray shielding material.
Adopts UV & IR Protection Shield, which uses high performance polycarbonate from Teijin Co., Ltd. as a shielding material that cuts UV (ultraviolet) and IR (infrared rays).
It has a heat ray shielding function that suppresses the rise of heat caused by solar infrared (IR), and it reduces the transfer of heat to the inside of the helmet while maintaining the most demanding "clear visibility" of helmets.
The temperature inside the helmet is measured in-house by illuminating an incandescent lamp (300 W)
