Costa Mag Bay Polarized Sunglasses in Blue Mirror

The Costa Mag Bay Polarized Sunglasses are engineered for anglers, outdoor enthusiasts, and anyone who demands clarity and comfort in bright conditions. Featuring 580A(R) Blue Mirror lenses, these sunglasses cut glare from water, snow, and reflective surfaces while enhancing natural colors for improved visual definition. The lightweight, durable frame ensures all-day comfort, making them perfect for long days on the water, trail, or road. Costa's Mag Bay model delivers the ultimate combination of optical performance and rugged construction. The 580A(R) lens technology not only blocks 100% of UVA, UVB, and UVC rays but also optimizes contrast and depth perception, helping you spot fish, terrain changes, and other critical details in your environment. The Blue Mirror finish reduces brightness without compromising color accuracy, while the corrosion-resistant frame withstands exposure to saltwater, sweat, and sun.
