FCS K2.1 Performance Core Quad fin Surfboard Fin Set
Kelly Slater's world beating template now in performance core, ideal for high performance in pocket surfing.
"These fins are perfect for down the line walls and long turns. I actually started using this fin 3 years ago when I needed a better fin for the long walled waves at Rincon. I've been on this same set of fins for over three years. They've been my magic set. I originally designed the K2.1 with beach breaks and barrels in mind, and I still use them in these sorts of conditions. With the K3's and the K2.1's you should be set for pretty much any sort of waves you find." -Kelly Slater
