Make Costa Del Mar® Mainsail 580P Polarized Sunglasses your first choice for a day on the water. These Costa sunglasses boast impact- and scratch-resistant polycarbonate polarized lenses that block glare, enhance visual clarity on the water, and safeguard your eyes from 100% of harmful UV rays. Outfitted with mirror coatings (on select styles) to further reduce glare, they boast Costa 580 technology that takes lens performance to new heights by eliminating glare from yellow light, blocking blue light to minimize haze and blur, and boosting red and green for deeper colors and sharper contrast. The large sport frames are made from tough nylon made using an eco-friendly bio-resin process (using castor oil instead of petroleum) to reduce emissions. When you wear Costa Del Mar sunglasses, you can feel confident that your eyes are protected and your new sunglasses aren't just another piece of plastic that'll one day wind up in the ocean. These Costa polarized sunglasses boast Hydrolite™ temple tips and nose pads for a more secure, comfortable fit, plus they're keeper-ready with lanyard holes. Costa Mainsail sunglasses include a case, a cleaning cloth, and a mfrs. limited 2-year warranty.
