Costa Gulf Shore Tortoise Frame Sunglasses GSH-10

Sleek, classic, and always a good look, Costa's Gulf Shore rimless sunglasses fit right in, whether it's an all-day fishing trip or a lazy day on the beach. Named for the Gulf Shores in Alabama, they are lightweight, polarized, and like the quartz that has washed down from the Appalachian Mountains thousands of years ago, these shades are timeless. 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.
