Cost Del Mar Tuna Alley Matte Black/Blue Mirror Sunglasses

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.
