The mountain is always the toughest rival. You have to be very well prepared to take on the dazzling sun and the cold winds. The Siroko K3 Himalaya adapt to the most extreme athletic environment thanks to their Special TAC 1.2 mm photochromic polarized interchangeable panoramic lens, with anti-fog layer and REVO cover. Their DrySky system is the best solution to fight back against the fog. The frame is extremely flexible and resistant. And they only weigh 27g. Includes polyurethane case, microfiber bag and spare bands.
Our photochromic lens is particularly sensitive to changes in light, adapting to the light conditions of each moment with maximum efficiency. They are 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 2 (42% light transmission) to Category 3 (11% light transmission) in less than sixty seconds, optimizing contrast and favoring visibility.
