Ever know a guide whose eyes seemed perfectly calibrated to local waters? Who could spot a bonefish among the shadows long before anyone else? Meet the Costa Rafael sport fishing sunglasses. These performance Costa Men's Angler fishing sunglasses with aggressive styling have a wide temple design and signature three-square hole venting keep those sacred eyes nice and cool. Sharks are in trouble, and without them the ocean ecosystem could collapse. Your purchase helps fund research expeditions aboard OCEARCH, a marine vessel and at-sea laboratory that generates critical data and puts science on the side of sharks.
