The Costa Del Mar Performance Crudo Sunglasses showcase a distinct blend of heavy-duty performance and conservation-driven styling inspired by the ocean's apex predators. This premium setup features an extra-large, wrap-around Matte Tiger Shark XXL frame equipped with exceptionally clear Blue Mirror 580G polarized glass lenses optimized for full sun conditions on open water. Costa's high-end 580G Lightwave glass technology targets and blocks harsh yellow light at the 580nm wavelength, drastically mitigating eye strain while enhancing natural contrast across marine fields. Built using resilient, lightweight bio-resin materials, the secure-fitting frame incorporates integrated side shields to shield your eyes from peripheral light bounce and whipping salt spray. Intended to endure the punishing environments of deep-sea navigation, these specialized lifestyle glasses are backed by Costa's signature limited lifetime manufacturer warranty.
