TECHNOLOGIES APPLIED: DOUBLE GLASS SYSTEM Double lenses and adequate ventilation are the two basic features that prevent fogging of the goggle lenses. The outer layer is made of hard polycarbonate or polarized glass, and the inner layer is made of cellulose acetate covered with an anti-fog layer. The layer of air between the glass creates a thermal barrier and eliminates fogging. LENS WITH UV 400 FILTER - The UV 400 filter blocks all three ranges of ultraviolet radiation: UVA, UVB and UVC. It guarantees 100% protection against the undesirable effects of eye exposure to solar radiation. REVO COATING - A coating consisting of 12-15 protective layers that reflects harmful sun rays and protects the eyes from ultraviolet radiation. A solution used in goggles and sports glasses. ANTI-FOG COATING - A special layer that prevents the lens from fogging up at very negative external temperatures. Improves visibility in difficult weather conditions. GOGGLES WITH THREE-LAYER SPONGE - Three layers of high- and medium-density polyurethane foam are covered with a soft, pleasant to the touch and hypoallergenic polarfleece material. HELMET COMPATIBLE GOGGLES - Fitting the goggles to a ski helmet increases the pleasure and comfort of use.
