Costa's Hatch Mossy Oak Camo Polarized Sunglasses protect much more than just your eyes. Fueled by your support, Costa is on a mission to protect the world's waters by promoting sport fishing, an environmentally friendly option for localnative cultures to sustain. You can do your part simply by enjoying the dedication Costa puts into its shades. When out protecting your own patch of water, you can take advantage of the Hatch's handsome nylon frame, lightweight enough to not weigh you down yet tough enough for any sport activity. Hydrolite nose and temple pads batten down the hatches during a storm, holding fast to your head even when soaking wet. The Costa 580 technology reaches far beyond the bounds of mere polarization. By blocking yellow light at exactly 580 nanometers, the lens relieves eye strain while enhancing color, improving your overall comfort. Crystal clarity is achieved by the hindrance of shortwave, high energy blue light, cutting haze and blur like you've never seen in sunglasses. Because a long day outside usually means a hefty helping of sun exposure, Costa ensured that the 580 polycarbonate lens are 100% UV blocking and glare cutting.
