Slightly used twin-fin set from Rainbow Fin Company (RFC) — a US-based fin maker that's been in the game since 1968 and builds a lot of their own material in-house rather than outsourcing overseas. This is their R5 template in bamboo core construction, which is RFC's premium tier: a real bamboo veneer laminated between fiberglass skins, giving a stiffer, more responsive flex pattern than a standard glass or plastic fin, with the visual bonus of the wood grain showing through.
Twin/keel setups like this are built for drive and hold through smooth, flowing turns rather than sharp pivoting — they're the classic pairing for fish-style boards, retro singles converted to twins, and anyone chasing that loose-but-connected, down-the-line feel in small-to-medium, punchy surf. Not the fin for tight, vertical surfing; that's not what this template is designed for.
What's included: the pair as shown (2 fins). No screws, plugs, or fin key — glass-on fins don't need them. Not compatible with FCS, FCS II. Only compatible with Futures boxes.
