Filtering reflective glare is essential for anyone on the water or outdoors. We sell only polarized sunglasses. Your Costas absorb 100% of UV light, providing you the best in light management and protection. The C-Wall coating provides extra scratch-resistance and a barrier that repels water, oil and sweat for easy cleaning. Made of 97% to 100% recycled fishing nets, our Untangled collection of sustainable frames includes Core Performance and Beach Lifestyle options that are as good for fishing as they are for the ocean.
