The helmet has a wind guard, normally for hanging and winter paragliding, it could provide full head protection. The overall aerodynamics is the best, you can get the best rectification effect. At a high-speed fly, the wind shield can resist high-speed airflow blowing through the mask edge seal, which can resist 180km's high-speed airflow. The wind shield is made of coated polycarbonate, outer surface hardening and anti-glare, anti-fog treatment inside the surface. The strength of the entire scope can withstand the impact of sand and gravel, and can not be broken, only split, the shape of the lens in the high-speed flight can not produce strong wind noise
