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.
