The ultimate performance shades for those who live for time spent on the water

In 1983, a group of hardcore fishermen in Florida came to a collective realization—the sunglasses they were using just didn’t cut it. Designed to take on the extreme conditions often found on the water, Costa del Mar has been bringing clarity and protection to generations of waterfolk ever since. Chock-full of performance technologies that improve airflow, seal out light, and wick away moisture, the Diego shades are finished off with Costa’s patented 580 lenses for enhanced clarity, color definition, and protection when the conditions demand nothing less.
