Costa Tuna Alley Matte Black Frame Sunglasses C-Mate TA-11

Costa's Tuna Alley sunglasses were named for the 15-mile stretch of sand that passes through azure Bahamian waters, famous for the Bluefin tuna's northern migration. These sunglasses were created with the angler in mind, using integral hinges, patented vent system and nylon that's as tough as you, all combined to give you visual performance that won't miss a thing. And as always, every pair of Costa sunglasses comes with a Costa Case, cleaning cloth, and manufacturer's Limited Lifetime Warranty.

Built By Hand

Setting themselves apart from the very beginning, nearly all Costa sunglasses are assembled by hand in their Daytona Beach, Florida, workshop. The building process includes no less than eight pairs of hands, all striving to maintain an attention to detail and adhering to the high standards Costa is known for. But at Costa they also know that you didn’t buy their products to stay still – and when something happens that isn’t covered by their Limited Warranties, Costa’s experts can quickly return frames and lenses to "like-new" standards*.

Beyond Polarized

Most traditional Polarized lenses work by only blocking reflective light, but Costa did more. Their patented 580® lenses go the distance by blocking the ideal amount of harsh yellow light and potentially harmful blue light, while simultaneously enriching beneficial reds, blues and greens. This all adds up to less haze, less blur, and improved clarity and contrast. And if those innovations weren’t enough, they offer both a lightweight, impact resistant polycarbonate lens (580P), and a more traditional glass lens (580G). So no matter which Costa lens type you choose, your worldview is about to go hi-def.

Looking After What They Love

At Costa, they love the water and they love everything living in it. From their Indifly Foundation to their Kick Plastic® initiative, they devote a substantial amount of time, resources, and efforts, to conservation, raising awareness, protecting fisheries, and enriching water-based communities.
