FCS M3 Natural Glass Flex Tri-Fin Set
The FCS M3 Natural Glass Flex Tri-Fin Set pairs FCS engineering with a natural glass flex layup, giving surfers a tri-fin setup built for predictable drive off the tail and a lively, flexible feel through turns. It arrives new from the factory and ready to drop into an FCS-compatible board.
Fin Construction and Measurements
- Sweep of 31
- Side base of 4.28 inches (109mm)
- Side depth of 4.41 inches (112mm)
- Surface area of 14.22 square inches (9,172 square mm)
Those numbers describe a tri-fin template with a moderate sweep and generous surface area, the kind of balance FCS uses to give surfers hold through turns without sacrificing the flex-driven release the Glass Flex construction is built for.
Who Rides This Tri-Fin Set
This set suits surfers who already ride an FCS fin box and want a fresh, flexible tri-fin option for everyday South Florida conditions, from small beach break peaks to longer period swells. A tri-fin, three-fin thruster layout is the standard, versatile choice for surfers who want maneuverability without giving up drive, whether paddling out at sunrise before work or squeezing in a session between errands.
Fitting, Riding and Caring for the Fins
Set the fins into the FCS boxes on the board, following the same tool and technique used for any FCS tri-fin install. After each session, rinse the fins and boxes with fresh water to clear out sand and salt, and store the board out of direct sun when not in use so the fin plugs and glass stay in good shape over time.
