There is a legendary 15-mile stretch of sand cutting through the deep blue Bahamian waters where the Bluefin tuna migrate north. The Costa Tuna Alley Sunglasses are for anglers looking to catch the big one, and named after this famous, amazing, and unique, underwater fish highway. With integral hinges, a patented vent system, polarized lenses and made from a tough-as-nails nylon frame these men's performance fishing sunglasses give you a competitive edge. Whether you’re out there fishing for fun, participating in a tournament, or this is what you do for a living, you’ve got a lot riding on your tackle, and (possibly) even a bit more invested in your boat. Give yourself a pair of glasses designed specifically for your sport, and choose between light impact resistant polycarbonate lenses or Costa’s Light Wave glass which is 20% thinner and 22% lighter than average polarized glass. Both options give you 100% UV protection with a patented molecular bonded scratch-resistance on the front and back of the lenses for stellar performance when you’re out on the water. Tight lines!
