The RayBan Wayfarer style sunglasses have been hijacked and made into almost any brand of shades you can imagine. I'll always be a bigger fan of the classic originals. however, these reasonably prices Vans are great alternative.
Personally, I'm notorious for wearing RayBans to the beach or to a party and loosing them. It's never a good feeling to realize that you lost $150 shades over a drunken stuper. So, finding cool shades that are also cheap enough to loose are a summertime necessity. These are those. Perfect beach day shades.
