Make Costa Del Mar® Mainsail 580G Glass Polarized Sunglasses your first choice for a day on the water. These Costa sunglasses combine 100% UV protection with polarized lenses and classic styling. Polarized lenses feature 580G LightWAVE® glass – the clearest in the industry. Outfitted with mirror coatings (on select styles) to further reduce glare, they're also scratch-resistant and thinner and lighter than average polarized glass. 580 technology filters out harsh yellow and harmful blue light, making colors brighter and objects sharper. 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.
