G10 is a legend. You cannot find something better in fins production. Excellent strength, stiffnes and durability. The profile of our fins is still radically thin with minimum hydrodynamic resistance. 2015 line of fins is characterized by UV RESISTANT fiberglass to delay avoid fast discoloration due to UV rays.
