K3 PHOTOCHROMIC ALPE D'HUEZ

K3 PhotoChromic Alpe d'Huez sport sunglasses. Optimized performance provided by their ultra-lightweight PC frame of only 27 grams and their interchangeable polarized Special TAC 1.2 photochromic lens. All styles in the K3 PhotoChromic collection count on our DrySky+ ventilation system to guarantee excellent vision in any situation. This product includes PU hardshell case, microfiber pouch and replacement rubber bands for temples and nose pad. Available K3 accessories: TR90 optical clip, anti-fog lens and clear lens. Our photochromic lens is sensitive to distinct changes of light by adapting to each moment in an extremely efficient way. Ideal for cloudy and clear days, and also for environments in which sunny and shadowy areas alternate. The K3 PhotoChromic lens controls the transmission of light independently, going from category 2 to category 3 in less than sixty seconds, optimizing contrast and favoring visibility. The percentages may vary slightly.
