The Costa Del Mar Man-O-War 580P Polarized Sunglasses are named after a creature most people avoid, but not anymore. These sunglasses are made for big adventures and big faces, with removable side shields for maximum protection against dust, sand, spray and anything else nature throws your way. The 580P Polarized lens filters yellow light while boosting red and green light and increasing polarization effectiveness. Because they are a polycarbonate lens they are resistant to hard impact and and scratching. Durability that has to be seen to believe. The frames feature integral hinges, Hyrdrolite temples and co-injected, cold-molding technology to deliver comfort and fit that lets you focus on dragging fish into the boat. Some people bleed saltwater. These are their sunglasses.
