The next step is understanding the materials FCS fins are constructed of:

FCS Fin materials explained



Glass Flex (GF)
Glass Flex has been formulated to replicate the flex and memory properties of hand layed fibreglass. It's advantages over other composite fin materials include stiffness, a more positive flex pattern (nice tip flex, little base flex) and remarkable flex memory. The precision of the injection moulding process ensures the highest accuracy in geometry in each fin produced.

Neo Glass
Lightweight, moulded fiberglass construction delivering pro standard performance. The high fiberglass content makes these fins stiff and responsive, and the engineered foils provide a consistent feel in a range of different conditions.

Performance Core (PC)
Performance Core material and construction is designed to deliver the feeling of a traditional fibreglass fin with the added performance of reduced weight. The RTM (Resin Transfer Moulding) process produces a lightweight fin with remarkable flex, a smooth feel and an impressive aesthetic. 

Performance Core Carbon (PCC)
Performance Core construction with hand laid carbon fibre designed to deliver controlled flex and enhanced base stiffness.

Performance Glass (PG)
Performance Glass material characteristics and flex pattern are identical to traditional fibreglass fins offering a stiff base with subtle responsive tip flex, amazing aesthetics and proven durability. PG fins are the perfect transition fin for surfers moving from fixed fins to the convenience, accuracy and performance of FCS.
