The K3 Tierra del Fuego are the most versatile photochromic glasses in the Siroko spectrum. They are apt for any cycling discipline thanks to their wrap-around design and anti-sliding temples, which provide great stability and comfort. They have a Special TAC 1.2 mm photochromic polarized interchangeable panoramic lens with anti-fog layer and REVO cover. DrySky anti-fog system. Extremely flexible and resistant PC frame. Maximum lightness: they weigh only 27g! Includes polyurethane case, microfiber bag and spare bands.
Our photochromic lens is particularly sensitive to distinct changes in light, adapting to the light conditions of each moment in an extremely efficient way. Ideal for cloudy and clear days, and for environments in which sunny and shadowy zones alternate.
The K3 PhotoChromic lens controls the transmission of light independently, going from Category 1 (54% light transmission) to Category 2 (41% light transmission) in less than sixty seconds, optimizing contrast and favoring visibility.
