The Costa Del Mar Performance Bulley Bait Sunglasses combine a lightweight bio-resin frame layout with maximum optical performance built for hardcore offshore adventures. This premium variant pairs a stealthy Matte Black XXL frame with high-clarity Blue Mirror 580G polarized glass lenses tailored specifically for the blinding glare of open water. Costa's elite 580G Lightwave glass engineering enhances true color definition and blocks out harsh yellow spectrums, vastly outperforming standard lenses in reducing optical fatigue. The robust wrap-around frame architecture ensures a secure fit against salt spray and heavy wind, while the exterior surfaces are reinforced with an oil-repelling, scratch-resistant C-Wall molecular coating. Designed to withstand continuous exposure to demanding marine environments, these high-end lifestyle glasses are protected by Costa's signature limited lifetime manufacturer warranty.
