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.
Fully-adjustable, nonslip nose pads were designed to further customize your fit and help reduce fogging.
Named after the small, chilled-out town in the Sea of Cortez, the Costa Loreto sunglasses are full frame and adventure friendly. Whether it's hanging on the coastal cliffs for which these Costa men's or women's sunglasses get their name or on any adventure on land or sea, these durable, versatile, polarized sunglasses can handle their own for any explorer.
