1. Topmost lace: it is the world's only mask with a cross-shaped lace at the top, which can prevent slide of goggle in violent motion. The lace can adjust size of the goggle and keep stability of mask.
2. Dismountable sunshade: the goggle has a dismountable sunshade. Users can put it on to prevent the sun's rays or dismount it at any time. It is practical and easy to use.
1. Anti-fog fan: the fan is specially designed and has been patented. It can be installed upper inside of the goggle, capable of removing fog on lens to keep the lens clear. It can keep clear and comfortable even if the wearer does exercise. 2. Super-wide-angle double-lens intercalated eyeglass: the 280°wide-angle lens meets all optic factors, through which you have a broad and clear visual field. Since a special water-unabsorbable sponge is set around the center between inside and outside layer, the center is hollow. Thus no water will be absorbed to form fogs. Moreover, the bending angle of both inside and outside eyeglass is the same, meeting all optical conditions. Therefore, no refraction or deformation will appear when wearers take a look at an object.
