An S1-rated windscreen works well when riding on cloudy and foggy days, as well as at night on the slopes with artificial lighting. Absorbing between 20 and 57% of light, they are clear and usually slightly tinted.

The lens has been coated with a special coating so that drops hitting the lens surface do not smear, but drip off. This does not impair visual acuity in difficult conditions. The lens itself is thus easy to keep clean, as the coating repels water and grease, and fingerprints rub off very easily.

Temperature fluctuations can cause unwanted fogging on the inside of the lens. To prevent this effect from occurring, the lens is treated with a special coating that prevents fogging. This increases safety and comfort when on the slopes.
