Named after the legendary 15-mile stretch of sand cutting through the deep blue Bahamian waters where the Bluefin tuna migrate north, these Costa Angler sunglasses are created to uncover and showcase the famous, underwater fish highway. With integral hinges, a patented vent system, 100% polarized and made from tough-as-nails nylon, these Men's Angler performance fishing sunglasses won't be missing much. All Costa lenses have 100% UV blockage for maximum protection and 100% polarization to kill reflected glare. Our 580 technology goes beyond polarization to produce the clearest lenses on the planet. Choose Glass for superior clarity and scratch resistance. Choose Plastic for a lightweight durable option.
