The lens with the S2 category is the most versatile. It will work well on a slightly cloudy day as well as when the sun is not too strong. It absorbs between 57 and 82% of light and has a slightly darkened surface.

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.
