FCS K2.1 Kelly Slater Glass Flex Surfboard Fin Set

FCS presents Kelly Slater's world beating fin template made with Glass Flex. Slater designed the K2.1 to be more maneuverable and faster off the top than the older KFin model. The side and center fins have different foils and flex patterns. The larger, more upright side fins have greater flex for tighter turns. The smaller, stiffer center fin adds control. Comes with three fins and a fin key. 4 5/16" base and 4 1/2" depth.
