Slack Tide - Bio Resin

**Polarized, ocean-friendly sunnies 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. Built with patented polarized lenses and laid-back frames made from durable and ocean-friendly bio-resin, these shades are ready for years of good times on the water.
