Named after the legendary 15-mile stretch of sand cutting through the deep blue Bahamian waters where the Bluefin tuna migrate north, these Costas were created to uncover and showcase the famous, underwater fish highway. With integral hinges, a signature venting system and Bio-Resin™ frames, these performance Costa Del Mar Tuna Alley Sunglasses won't miss much beneath the surf.

Costa advanced fly fishing polarized sunglasses are handcrafted for life on and off the water. Built to be expedition tough with lenses that eliminate glare and reduce eye fatigue by preventing the eye from absorbing the horizontal wavelengths of light reflected by water. Costa Del Mar sunglasses offer superior design, the highest quality manufacturing, and the best-polarized lenses on the planet.

The Blue Mirror Lens is best for bright, full-sun situations on the open water and offshore. Ideal for boating and fishing in deep water, where there is open reflective water and harsh sun. Featuring a grey base and 10% light transmission.
