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, polarized and made from tough-as-nails nylon, these men's performance fishing sunglasses won't be missing much. Costa believes in products with a purpose, and is proud to help support OCEARCH in its mission to protect the sharks that keep our ocean ecosystems balanced. The OCEARCH Collection helps fund research expeditions that generate critical data and put science on the side of sharks.
