Modern racing history starts at the north turn of the course that ran along Daytona Beach from the '30s to the '50s. The Costa North Turn Polarized 580 Polycarbonate Lens Sunglasses pay tribute to this historic era with a bold profile and timeless styling. The large fit offers optimal coverage from the central Florida sun and the durable scratch-resistant lenses are polarized to eliminate the glare coming off the water.
