FCS II Matt Biolos Fin

These fins are designed for open-face waves where you need to generate speed and hold a line. They excel in point and reef breaks where you can carve through longer, more powerful sections.

The stiff flex construction provides maximum energy return, meaning you get more drive and speed out of your turns. It is ideal for surfers who want a responsive feel and the ability to push hard through maneuvers without the fin feeling loose or washy.

These fins use the FCS II system, which is designed for tool-less installation. They will fit any surfboard equipped with FCS II fin boxes, but they are generally best paired with performance shortboards or hybrid shapes.

The Medium size is typically recommended for surfers weighing between 65kg and 80kg (145-175 lbs). If you are on the lighter or heavier end of that spectrum, you might find the fin feels too loose or too stiff, respectively.

The tapered tip allows for quick, agile maneuvers and release off the top of the wave. It balances out the wide base, ensuring that while you have plenty of drive, you can still pivot and redirect the board easily.
