FCS II Christenson Keel Sale (M-L / Performance Glass / Black)

New keel template we've worked on with Chris Christenson that compliments both function & aesthetic. Performance Material Size Overview Designed with plenty of curve in the leading and trailing edge to provide smooth rail to rail transitions. A thicker, flat foil provides grip through big turns and open face waves. Board Types Designed to fit the FCS II Fin System. Recommended for all board types including fish, funboard and twin fin boards. Performance Glass Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations. Medium - Large New Sizing for Specialty Fins You may notice new size ratings for our Specialty Fin Range. Previously, all Specialty Series fins were rated an XL. To better reflect fin sizing, we now have 3 new size categories: S-M, M-L, and L-XL.
