Up for sale is a George Greenough "4A" flex fin, 8.0" — the mid/smaller size of Greenough's iconic template, in natural amber fiberglass rather than a pigmented colorway.
At 8.0", this size steps down from the longboard-specific 10.5" and moves into speed-shape and mid-length territory — it also works on shortboard single fins and 2+1 setups. It's a great fit for intermediate to advanced surfers who want that classic Greenough feel: a full base for drive and hold, tapering into a flexible tip that loads and releases through turns. Works well across conditions, from small mushy days where you need the extra drive, up through punchier, more powerful waves where a stiffer base keeps things locked in.
This is a single fin, sold individually — no screw/key included unless noted in your order (check listing photos for exactly what's pictured). Fits glass-on / single-screw box style longboard setups only — please confirm your board's fin box before buying, as this is not FCS, FCS II, or Futures compatible.
