Costa Del Mar Brine II Sunglasses, Matte Black/Gray 580p, 59mm Polarized 100% UV, Hydrolite Grip

The Costa Del Mar Brine II sunglasses are a large-fit, water-ready wrap frame with grey 580P polarized lenses and Hydrolite comfort for secure all-day wear.

Designed for anglers, boaters, and anyone who spends long hours outdoors, the Brine II blends protective 8-base wrap coverage with lightweight Bio-Resin durability. The 59 mm lens sits in a rectangular matte black frame that keeps glare under control and preserves true color on the water. Polarized 580 Polycarbonate lenses combine impact resistance with Costa’s signature polarization to reduce reflected glare while offering 100% UV protection. Practical touches such as double-injected Hydrolite on the nose and temple tips plus retainer-ready temples make these sunglasses a dependable option for active days under sun and spray.
