Lightweight, photochromic, crisp and clear - Serengeti Bormio Sunglasses

So I was a long time Ray Ban guy, until they went the lame route and stopped offering the Predator 8 wrap style. I enjoyed the quality glass lenses. I also had Serengeti's for my driving glasses. The lenses the have accent the important colors when driving Red, Green, Amber and they're polarized to cut down on the retina burning glare. I have the Bormio polarized PhD Drivers lens, which have the nice 8 wrap. Love the darn things. They darken up when it's a really bright day, and then when it starts to get dark they lighten up.
I sometimes forget I have them on because they are so clear and light. Comes in a nice case with a hefty 'towel' to wrap 'em up in and also to clean the lens. I anticipate they will last for years.
