These shades are ready for speed. Mirrored rectangular lenses are encased in curved plastic frames that wrap slightly around your face to keep you aerodynamic and so that the sunglasses stay secure even during action. Wide arms narrow into narrower, slightly curved earpieces. Tiny vents allow air to circulate behind the frames to prevent condensation and heat buildup. Arms are decorated with a metallic tag containing the Biohazard logo. Choose all-black or all-white frames to keep the look pared down or opt for a bit of fun color along the upper and lower rim edges: red, yellow, lime green, or aqua. These sunglasses are sold in bulk by the dozen.
