Costa says its newest style of sunglasses honors the fight of the brutish, sought-after giant trevally. Trevally frames are made from a nearly indestructible bio-based resin and come with integral hinges and hypoallergenic nose pads. They come in unisex colors, including tortoise, matte black, matte orchid and matte tortuga fade. Customize your Trevally sunglasses using any of Costa's polarized 580 glass or polycarbonate lenses, as well as prescription lenses. The glasses start at $159.
