Looking to turn your favorite Thruster set into a Quad? This pair of Quad Rears can be combined with any Futures front fins to suit your riding preference, board design and waves. With a flat foil, these rears provide increased responsiveness, drive and hold, and will favor boards that have the rear boxes set closer to the rail, away from the stringer.
Techflex is stiff like Fiberglass but lighter than Honeycomb. The ultimate in flat foiled fins, great for powerful surfers or powerful surf.
Flat Foil - Flat foiled fins break free sooner, and are better ay controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
