K3s PhotoChromic Blue

Our photochromic lens designed for your Siroko K3s is especially senstitve to distinct changes in light, adapting to the lighting conditions of each moment in an extremely efficient way. Ideal for low visibility moments, morning routes and training sessions, partly cloudy days or when you need some extra protection against gusts of wind.

The K3s PhotoChromic lens controls the transmission of light independently, going from category 1 to category 2 in less than sixty seconds, optimizing contrast and favoring visibility (the percentages may vary slightly). The lens does also count on our DrySky ventilation system and anti-fog coating to guarantee excellent vision and avoid condensation.
