Built for Every Adventure on the Water
The Costa Del Mar Loreto is a full-frame metal aviator designed for people who don't slow down when the scenery gets good. Named after the legendary coastal destination on the Sea of Cortez, the Loreto combines refined styling with genuine optical performance, ready for everything from open-water fishing to a long afternoon on the shore.
580G Polarized Glass Lenses
The Loreto is fitted with Costa's 580G lens technology: polarized glass ground to the 580 spectrum-filtering standard. The 580 designation refers to Costa's proprietary light-filtering approach, which cuts yellow light at 580 nanometers to reduce haze and sharpen contrast in bright, reflective environments like open water and white sand. Glass lenses deliver sharper optics and greater scratch resistance than plastic alternatives, and the polarization filter eliminates horizontal glare from water and wet surfaces so you can see clearly through the surface.
The Base 6 lens curve wraps the lens closer to the face than a flat lens, improving peripheral coverage and reducing light intrusion from the sides. That is a practical advantage when the sun is low on the horizon.
Full Metal Frame and Fit
The Loreto frame is a full-coverage metal aviator construction. The lightweight metal build keeps the frame durable without adding weight to a long day of wear. Temples feature a comfortable tip design that holds the frame securely during active use.
Adjustable nosepads let you dial in the fit for your face rather than accepting a fixed bridge position. The Regular fit is designed for a broad range of face shapes, keeping the frame stable and the lenses properly centered in your field of vision.
Costa Del Mar: Made for the Water
Costa Del Mar is an American polarized sunglass brand built around the needs of people who spend serious time on and around the water. Every Loreto is backed by Costa's optical standards and the durability expected from a performance fishing and outdoor brand. Shop the Loreto at Island Water Sports, in store in South Florida or online.
