Named after the elusive Roosterfish, The Costa Rooster sunglasses are a tribute to all the fly fisherman who have had to see-and-run-far. 100% polarized, durable and made with side-cupped frames, these Costa men's Angler and Voyager sport fishing sunglasses are perfect for the pursuing adventure and for fighting fish, instead of glare. 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.
