With west-coast style, the Costa Half Moon Polarized 580P Sunglasses give you a sporty look that contains technical features. Polycarbonate lenses are polarized to filter out rays, and are impact-resistant and so lightweight you could almost forget you're wearing them. Hydrolite nose and temple pads keep you comfortable throughout long days of wear, and when you finally do take them off, the C-wall molecular bond protects the lenses from scratches until you can get them into the included case.
