Cycling and running without changing your eyewear.
 
Sportchromic photochromic lens in Nylon (NOT Polycarbonate) to quickly adapt to every light condition mantaining, like the whole X Series, an optical perfection even superior to the mineral glass.
 
 A purity that brings a better reaction rate and a greater color variation. Accurate and steady thanks to the grip guaranteed by the adjustable nose pad, perfect fit for men and women.
