The well-known, durable, everyday sunglasses for the sea (I get the same ones every 3-4 years). These specific ones have a slightly greenish lens, instead of gray/black - but it doesn't bother me. They cover the eyes well and don't let sun in from the sides.

I bought them without seeing them in person. In the end, it was an excellent purchase. The polaroid lenses are guaranteed, the frame is flexible and lightweight. You pay for substance and not for designer.
