Product Description From yoga to running and all life activities in between, the Women's Oakley Top Knot cat eye sunglasses will keep you looking fashionable all day long. Featuring Oakley's Three-Point Fit system that relieves pressure points by redistributing the weight across the nose bridge and temples, the Oakley Top Knot sunglasses are constructed of durable, lightweight O Matter with C-5 alloy metal and Unobtainium nose pads for a no slip grip and all day comfort. Each pair of Top Knot sunglasses sport Oakley's famous Plutonite lenses that block 100% of all UVA, UVB, UVC and harmful blue light up to 400mm. The no-snag metal inlay also prevents the Top Knot sunglasses from getting caught in your hair.
