If you haven't worn a pair of sunglasses with gradient lenses, you need to try these stylish shades by Dxtreme. Designed for active men, these sunglasses give you privacy as well as ultraviolet protection, while giving you a cool and mysterious appearance. The frames are made of metal, and the arms are made of plastic -- a combination that gives the glasses flexibility and strength. The arms are straight, starting thick and tapering to the ear, and featuring the Dxtreme logo on the side.
