Description

Classics combine for standout style in our Obsidian Fast Lanes Rx sunglasses and eyeglasses. This colorway has become a staple for its gradient that fades from black to clear, along with subtle transparent accents throughout the arms and fronts. Not to be outdone on safety, Obsidian Fast Lanes Rx sunglass lenses also feature polarized lenses with UV400 protection and impact resistance for wherever life takes you. Top the whole thing off with dark chrome ‘K’ detailing and prepare to smolder
