The Costa Crudo in Matte Tiger Shark is paired with Costa’s premium Blue Mirror 580G polarized glass lenses. The Blue Mirror lens uses a gray base with 10% light transmission and is designed for bright, full-sun conditions, offshore fishing, boating, deep water, and highly reflective open water. Costa’s 580G glass provides high optical clarity and scratch resistance, with the mirror encapsulated between layers of glass and C-Wall® coating to help repel water, oil, and sweat.
