Inspired by ocean surfing quads, the Velvet The Quad Fin Set are designed to be used as on their own as a set of 4 fins. With their lightweight honeycomb core and fiberglass exterior, these fins provide a snappy flex that's ideal for larger surfers and/or experienced surfers that just want a lot of drive and hold. Heck if you want, you could even run these as a twin fin by removing the rear fins for a looser feel too.
