You won't find any plastic shell: the single lens in tempered glass, ultra-resistant and 4mm thick, is surrounded by 2 types of overmolded silicone to obtain an ergonomic skirt that adapts perfectly to every face. The silicone inside the skirt has a matte texture to eliminate any reflections. The edge of the mask is shiny and slightly curved to increase the grip area, reducing annoying marks on the face for optimal comfort even during prolonged use. The double-button 3D tilting buckle makes it easy to adjust the silicone strap of the mask.
