Filtering reflective glare is essential for anyone on the water or outdoors. We sell only polarized sunglasses.

100% UV Protection

Your Costas absorb 100% of UV light, providing you the best in light management and protection.


Scratch Resistant and Durable

The C-Wall coating provides extra scratch-resistance and a barrier that repels water, oil and sweat for easy cleaning.

Named after the legendary 15-mile stretch of sand cutting through the deep blue Bahamian waters where the Bluefin tuna migrate north, these Costa angler sunglasses are created to uncover and showcase the famous, underwater fish highway. With integral hinges, a patented vent system, polarized and made from tough-as-nails nylon, these men's performance fishing sunglasses won't be missing much.
