Costa Del Mar Man O War Sunglasses

High Tech. High Performance. The ultimate lens. When only the best will do. Patented Costa Wave 580 glass lenses incorporate an advance filtering compound which eliminates much of the yellow light resulting in deeper colors and sharper contrasts. 100% UVA and UVB protection plus 100% polarization. Glass is the most optically correct lens material and Costa's Lightwave glass lenses are 20% thinner and 22% lighter, and still exceed federal standards for impact resistance. Man O War sunglasses have removable side shields.
