The Costa Del Mar Man-O-War 400G 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. Polarization eliminates glare which means, you can see them before they see you. With durability that has to be seen to believe, these frames feature integral hinges, Hyrdrolite temples and co-injected, cold-molding technology to deliver comfort and fit that lets you focus on the the fishing.
