The gannet is a large and gorgeous sea bird that undertakes daring voyages across thousands of miles of ocean every year. Similarly, the Costa Women's Gannet 580P Polarized Sunglasses feature a big, bold, and beautiful frame for a look that stands out, and they're equipped with the features needed to embark on awe-inspiring adventures.

Polarized lenses equip these sunglasses for life at sea by eliminating glare, and they're made from 580P polycarbonate for a lightweight feel that won't weigh on you during long days on the water. They're also scratch-resistant for durability during arduous voyages, and Hydrolite pads help them stay firmly on your face when the waves get rough. Of course, with their laid-back look, they're also just as at home lounging by the pool if that's more your speed.
