Costa MainSail Polarized Sunglasses
The Costa MainSail Polarized Sunglasses are built for anglers and boaters who want premium eye protection, exceptional clarity, and all-day comfort on the water. Featuring a full-wrap design with Costa's renowned 580® polarized lens technology, the MainSail helps eliminate harsh glare while enhancing color, contrast, and detail, making it easier to spot fish, read changing water conditions, and navigate confidently in bright sunlight.
Constructed with a lightweight, durable bio-resin frame, the MainSail is designed for long days offshore, inshore, or along the beaches of Hatteras Island. Hydrolite® rubber nose pads and temple tips become grippier when wet, helping keep your sunglasses securely in place whether you're casting from the surf, running offshore, or relaxing on the beach. Frank & Fran's proudly serves anglers throughout the Outer Banks and ships nationwide.
