The new EVO glasses have an enveloping shape, ideal for protecting your eyes from the sun – naturally – but also from the wind and bad weather when cycling. They are so light (27 g.) that you do not realize that you are wearing sunglasses. Like all Björka cycling glasses, the EVO are delivered with 2 interchangeable high definition polycarbonate lenses: a transparent lens (category 0) practical for winter and during cloudy weather, and a mirrored lens of category 3, 100% Sun Creme. As an option, we offer you an Evo photochromic lens which will ensure you permanent comfort – whether it is raining or shining bright. You have the choice of color, since there are 6 colors of Evo cycling glasses.
