Best ones for summer time. Ray Ban gives you vintage feel thanks to Caravan sunglasses. These sunglasses have square lens and frames, so it gives you stylish look. If you can’t choose what kind of model of sunglasses to buy, then for sure take Caravan sunglasses. This model suits every man, no matter what kind of face you have, oval, round; this model will suit you for sure. This model is worn by many actors and stars. These sunglasses come in different colors and lenses. As you can see below, there are different colors of frames. MY favorite option of Caravan sunglasses is that some of models can be found with three flip out lenses (with different lens colors).
