This product can be attached to a work helmet instead of a mask. With the aim of reducing the risk of heat stroke by wearing a mask in the summer, we jointly developed the product that has both design and functionality while giving consideration to breathability and measures against airborne droplets. The inside of the shield is antibacterial processed and has a UV cut rate of approximately 99% and a heat shielding effect. GK Dynamics collaborated not only in designing the product but also in formulating the product concept and business policy, aiming for early commercialization.
