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.

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.
