Gerry Lopez signature Tri-Quad set. Suited to power surfers who like to carve and push hard against their fins.

The FCS II Gerry Lopez Tri-Quad SUP Surf Fins are Gerry Lopez's signature fins made for great response and maneuverability whether you're riding a longboard or surfing a SUP. You can customize between directional flow on the open face and pivotal control when making your way through turns. These fins show their true colors when on open-faced, down-the-line waves, and in your favorite point or reef breaks. They work great on mid-lengths boards, longboards, and SUPs. With the FCS II tool-less build, you can easily insert, remove, and adjust the fins as needed with no tools or screw and plate required. It'll fit a wide variety of existing single fin boxes.
