Here's what other sites are saying:
Life on the high seas doesn't have to end just because dry land awaits after stepping off the boat. Optimized for salty sea dogs, but boldly oversized enough for landlubbers, the Costa Del Mar Double Haul Polarized Sunglasses are the last sunny you'll ever need. The Double Haul is fitted with Costa's new featherweight 580P polarized polycarbonate lens--which exceeds ANSI impact resistance standards, while blocking yellow light and increasing polarizing efficiency. The 580P also features Costa's proprietary C-Wall coating; a fused application which blocks scratches and repels water, oil, and dust. After spending over two years on its development, Costa thinks the 580P is the most optically correct, and technologically advanced lens on the planet, and thinks you'll be inclined to agree after bringing them out on your next adventure.
