Costa DelMar Blackfin Sunglasses with Matte Black Frames and Blue Mirror 580 Polarized Glass Lenses. Theses are our clearest lenses. You might have gallons of brine in your face and a 600 pound Marlin on your hook, but these sunglasses still won't slip. The Hydrolite™ co-injected lining takes care of that, and the flexible frame means serious comfort. Blackfin pushes the edge in sunglass performance--so you can push it everywhere else.
