FCS II Matt Biolos Fins

These fins are designed for critical, overhead conditions. Their template excels when you need to hold your line in steep sections and perform tight, precise turns in the pocket.

The carbon-infused core makes these fins significantly stiffer than standard fiberglass or plastic options. This rigidity provides a highly responsive, snappy feel that allows for explosive maneuvers and immediate energy transfer.

Yes, this is a five-fin set, which gives you the flexibility to switch between a thruster setup for more pivot and control, or a quad setup for increased speed and drive down the line.

These fins use the FCS II system, which is designed to click in and out without screws. They are compatible with all standard FCS II fin boxes found on most modern performance shortboards and hybrids.

This template is ideal for power surfers who prioritize speed and tight, aggressive turns. If you find yourself surfing punchy, hollow waves and want a fin that won't flex out during high-speed maneuvers, this is a great choice.
