I've been shopping/searching for new sunglasses for a few months. It was becoming a chore until I was found this site at amazon.com. All the old & new styles...cheap ones & $$$$$ ones, high quality & drug store versions. I wanted high quality for driving, these Serengeti's fit the bill. They are polarized, so no hot reflections, top up or down. The fit is perfect. They were shipped right away, and came with a hard carrying case so they'll stay in terrific shape. I would shop and buy again from this partner.
