Some sunglasses could really be for a guy or a girl. Not so with the Oakley Mens Oil Rig Sunglasses. These shades are more about man-sized drill-bits. Luckily you dont have to have a face made out of metal to handle the weight of the Oil Rig SunglassesOakley made these frames with lightweight, durable O Matter. The Oil Rig curves around your face so the frame wont stick out on the sides of medium or large-sized chevy chases. The lens maintains clarity throughout the entire curve and filters out 100 of all UV rays.
