Lost my Aviator on a beach trip and then wanted to try something different. I've been told Maui Jim's supposedly makes the best polarized lenses for the mainstream markets, and that's why I bought these. It's well-maid polycarbonate lenses, which are light and very suitable for beach activity or any other sports. I also like the way the frame fits, as it curves to wrap around my face. Haven't used it very much but it does feel like durable materials. Hopefully it will last longer than my previous sunglasses.
