FCS Kai Sallas Fin. Designed and tested by Hawaiian waterman Kai Sallas, this new high performance longboard template allows for acute directional changes without losing drive or hold. Made from FCS’s signature Performance Glass, this fin boasts a stiff base (for added forward acceleration and hold) and smooth flex through the last 1/3 of the fin (for increased responsiveness). Template features extra length at the base of the trailing edge that quickly tapers to a narrow tip. It looks as sharp as it performs. Ideal for 2 + 1 set ups. FCS.
