Carbon Fiber:
Carbon Fiber has one of the best
strength to weight ratios of any material. The energy you load up on a
carbon fiber fin comes back in a burst of energy because of its
Resiliency. Fiberglass: Stiff and tough for heavy conditions. Or surfers that appreciate very stiff fins. Honeycomb: Lightweight foam hex core glass fin that has the look and feel of a glass-on fin.
Engineered with a medium flex pattern, stiffer than Blackstix but more flexible than fiberglass and Techflex. Natural Composite:
Molded-resin with long-fiberglass matrix, this composite material fuses
into a snappy and lightweight fin that retains the proper flex pattern
for performance. Texalium: Aluminized Fiberglass that is stiffer than fiberglass, but more flexible and springy than carbon.
