Flying Diamonds CJ Involvement Fin-Black

This fin is a classic. Drawing on the simple and proven designs of our forefathers, we added subtle elements to this design to optimize it for speed and added power through turns. Clean, simple lines and perfect mid-range flex. The Function first concept makes this fin one of the easiest riding fins weve ever come across. Lots of control and drive in a beautiful package. A great choice for any single fin longboard.
