These sunglasses are made for sports and feature a lightweight construction with strong plastic that holds its shape and stands up to rough use. Made for men by Oxigen, the frame is made of plastic and designed for any outdoor activity. The arms come off the temples and stay straight back to the slight curve at the ear. The Oxigen logo is seen on the side in either white or black writing. The lenses are set in the semi-rimless face and offer excellent UV protection to your eyes.
