Costa Diego Polarized Sunglasses

The Costa Diego Polarized Sunglasses combine modern styling with Costa's renowned optical performance, making them an excellent choice for anglers, boaters, and outdoor enthusiasts. Featuring Costa's legendary 580® polarized lens technology, the Diego delivers exceptional glare reduction, vibrant color enhancement, and crystal-clear vision whether you're fishing offshore, relaxing at the beach, or spending the day on the water.

Built with a lightweight, durable bio-resin frame, the Diego is designed for lasting comfort during long days outdoors. Hydrolite® nose pads and temple tips provide a secure fit by increasing grip as conditions get wetter, helping your sunglasses stay in place while casting, boating, or exploring the coast. Whether you're surf fishing the beaches of Hatteras Island or enjoying a sunny day around town, the Costa Diego offers premium performance with everyday versatility.
