K2.1 FiberGlass Flex Pack Thruster + Quad 

The K2.1 fins are inspired by flagship fins of the best surfer of all time. The side fins have a different shape, foil and flex from the central fin.

The side fins are wider with less sweep and more flex for tighter, faster turns. The central fin is stiffer and smaller for increased control.

For quad system, the rear fins are also smaller and more rigid.

These are the perfect fins for radical surfing in the pocket of the wave.
