[ UPDATED 2014 ]
My first good pair of sunglasses was a pair of Revos. This is back when they were good.
They had really good layering, and I remember that whenever I came home to California from the Military I would see my home through Revos and feel even more like the Bay Area was the best place on the Earth.
I bought a pair of Revos back in the early 90’s, and I had them until perhaps 2008. I was doing a consulting job up in northern New York state, and I left them in the sun visor of my rental car at the airport in New Jersey.
I miss those sunglasses to this day.
