The Costa Del Mar Rafael Polarized Costa 580 Polycarbonate Lens Sunglasses are aggressively styled and have a wide temple design and signature three-square hole venting to keep those sacred eyes nice and cool through all of your adventures on the water. The Costa 580 polycarbonate lenses are lightweight, impact- and scratch-resistant for a long life, and polarized to kill the harsh reflected glare and lessen eye strain. The TR-90 nylon frame is built tough while remaining lightweight, and the included hard case provides a safe home for your sunnies when the day is done.
