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.

  • Bio-resin frames are lightweight, durable, and better for the planet
  • Patented, polarized gray 580P polycarbonate lenses reduce glare and eyestrain while providing 100% UVA/UVB protection for long days offshore
  • 580 lenses enhance reds, greens, and blues while cutting out yellows for high-definition vision
  • Laid-back, casual frames blur the line between performance and lifestyle wear
  • Includes premium hard carrying case and cleaning cloth
