Built for the Coast, Designed to Last
The Costa Del Mar Sullivan brings a relaxed, water-inspired silhouette to one of the most optically advanced lens platforms available. The rounded square acetate frame carries a rich tortoise pattern with a matte finish that keeps the look understated while the 580G Blue Mirror lenses do the heavy lifting where it counts: on the water, in the surf, or anywhere the glare is real.
The Sullivan is part of Costa's Del Mar collection, a lineup built around the idea that serious sun protection and genuine coastal style are not a trade-off. The frame shape is classic without being dated, and the slim temples keep it comfortable under a hat or helmet.
Costa 580G Polarized Glass Lenses
580G is Costa's flagship glass lens technology. The "580" designation refers to the lens's ability to filter the specific wavelengths of light, yellow, blue, and ultraviolet, that create glare and visual noise on the water. The result is sharper contrast, truer color rendering, and less eye fatigue on long sessions in the sun.
Glass (G) is denser and harder than polycarbonate, which means it resists surface scratches better and maintains optical clarity over years of use. The Blue Mirror coating on the outer surface adds an additional layer of glare suppression and is well suited to open-water, beach, and bright-sky conditions. All 580G lenses provide 100% UV protection.
Frame Construction and Fit
The Sullivan frame is crafted from water-inspired acetate, a material that holds patterning and color depth that injection-molded plastics cannot replicate. The matte finish reduces reflections off the frame itself and gives the piece a more refined, muted look compared to gloss finishes.
- Frame fit: Regular
- Lens curve: Base 6, a moderate wrap that keeps the lens close to the face for better peripheral coverage without an aggressive sport look
- Nosepad: Fixed (non-adjustable), sculpted into the frame
- Costa logo badge on the temple
The Sullivan for Men
The Sullivan is designed and sized for men, with a regular fit profile that suits a broad range of face shapes. The rounded square shape softens angular features and works equally well off the water: at the dock, at the restaurant, or running errands along the coast. It is a one-frame solution for anyone who does not want to switch between sport and lifestyle sunglasses.
