Performance like a goggle!
All I can say is wow! I own 25 pair of sunglasses including many Maui Jim's, Oakley's, Kaenon, Ray Ban, Persol, Vuarnet, and others. The Costa Del Mar Tag Polarized Sunglasses with the Costa Blue 580 lens is simply amazing. It is seeing in high definition. In extreme bright sunlight, the goggle like wrap frame cuts out any possibility of unfiltered light leaking in from the top or sides. They are incredibly comfortable, in large part because of the flexible temples, but also due to the light weight of the new Costa glass lens. Rubber in the nose piece, and the temples make sure they do not slip off your face even in high temperatures where sweat can cause an ordinary pair to slip down your nose. Contrast and color definition is incredible. Five stars for sure!!!!
