FCS II MF Fins in Glass Fibre Fusion
If you have been comparing fiberglass FCS fins, this MF tri-fin set uses FCS's Glass Fibre Fusion construction and is built to fit the FCS II Fin System as a complete three-fin set.
What You Get
- A full tri-fin, three-piece set built in Glass Fibre Fusion construction
- Designed to fit the FCS II Fin System's tool-free plug base
Why Fiberglass Construction Matters
Fiberglass based fin constructions are generally chosen by surfers who want a stiffer, more direct feel underfoot compared to softer plastic fins, since a stiffer fin transmits more of the rider's input into the turn rather than flexing it away. That stiffness is the main reason surfers researching fiberglass FCS fins look at a Fusion or glass built template over a standard nylon composite one.
Who This Set Fits
This is a tri-fin replacement for any surfer already running an FCS II equipped board, whether upgrading from a stock fin set or replacing worn fins. Confirm your board is drilled for FCS II boxes before ordering, since FCS I and FCS II bases are not interchangeable, a common point of confusion for surfers switching fin brands.
Installing and Caring for the Set
- FCS II fins insert and release by hand, no fin key required
- Rinse fins and fin boxes in fresh water after every session to clear salt and sand
- Dry fins before reinserting so grit does not get trapped in the plug mechanism
- Store the set somewhere it will not get crushed or bent between surfs
Backed by FCS and Island Water Sports
FCS designs its fin range in collaboration with the world's leading surf athletes and surfboard shapers, and its fins are the preferred choice of the world's best surfers and shapers.
