Truly enhance your fishing experience with the Costa Bomba C Mates Reader Sunglasses. They feature C Mates reader technology to help you see the small stuff such as the eye of a fishhook or details on a map, without the visible line around the bifocal area that you usually see in readers. The lenses are also polarized to eliminate glare so you can see clearly beneath the water's surface, and the large frame size and wide arms provide total coverage for better protection from the sun when you're out on the open sea or in a high altitude mountain stream. And of course these shades feature the legendary optical clarity and quality you expect from Costa, all backed up by a lifetime warranty. What are you waiting for'
