With a large fit and a straightforward style, the Costa Del Mar Caye Polarized Sunglasses protect your eyes whether you're relaxing under the sun or looking for where the fish are hiding. Costa 400 polarized glass lenses block harmful UV rays as well as harsh glares so your eyes stay happy and healthy in the sunlight. The glass lenses are also 20% thinner and 22% lighter than standard glass polarized lenses, and they resist scratches so you can enjoy these sunnies for many years of boating and fishing. Costa Del Mar made the frame out of co-injected nylon for durability, and the stainless steel spring hinges won't corrode if you decide to take a dip. The six base curve means these shades wrap a little bit around your face, halfway between a sport-style wrap and flat lifestyle sunglasses. An included hard case helps with safe travel.
