You didn't buy a boat just so you could see half the sights through sub-par sunnies. Costa Del Mar made the Polarized Half Moon 580G Sunglasses with real, pure glass lenses—you know, the stuff that plastic and polycarbonate lenses poorly mimic. Each glass lens is 22% lighter and 20% thinner than the competition, and they are virtually scratch-proof for long-lasting durability. Costa encapsulated mirrors into each lens for a water-worthy look whether you're cruising the coast or coasting to cruise. The lenses are also polarized, so you won't miss the chance of docking into an empty harbor due to some unwanted sun glare.
