Costa Montauk 580G Polarized Sunglasses Named after the end of Long Island where monster fish congregate, this frame will have you ready at the reel. Fishing functionality is the focus of Montauk, a large 8-baser, full-wrap, highly ventilated frame, designed to block peripheral light and manage sweat. The Hydrolyte nose and temple pads assure a secure fit for the open water. They're also keeper-ready when the sun goes down.
