FCS II Matt Biolos Fin

This template is designed for power surfing. The wide base and curved trailing edge are engineered to help you generate drive and hold through critical turns, making it ideal for surfers who like to push hard against their fins.

PC AirCore construction makes the fins stiffer and lighter than standard fiberglass or composite fins. This stiffness translates to immediate energy transfer, giving you more speed and responsiveness when you load up for a turn.

Yes, this is a versatile tri-quad set. You can ride them as a thruster for a more traditional, pivot-oriented feel, or switch to the quad setup when you want more speed and hold on open-face waves.

No, these are FCS II fins. They are designed for the FCS II tool-less system, which allows you to click the fins in and out without screws. They will not fit into older dual-tab boxes that require grub screws.

FCS generally recommends the Large size for surfers weighing between 165 and 200 pounds (75 to 90 kg). If you are on the heavier side of that range or prefer a fin with more hold and drive, this size is a solid choice.

These fins excel in open-face, down-the-line waves, such as point or reef breaks. The design provides the stability needed for carving long lines and the release required for sharper, more aggressive maneuvers.
