3.7" + 7.5" 2+1 Fin Set – natural Pro Glass | FCS compatible Side Fins (3 fins)

Balanced trim, controlled turning, and dependable stability for longboards and mid-length surfboards.

The 3.7" + 7.5" 2+1 Fin Set in natural Pro Glass is a traditional three-fin configuration designed to provide stable trim, smooth rail engagement, and predictable turning response across a wide range of surf conditions. The set includes a 7.5" classic center fin for primary hold and directional control, paired with 3.7" side fins that add rail stability and assist turning without excessive drag.

Constructed from natural Pro Glass fiberglass, each fin delivers consistent flex characteristics, structural durability, and reliable energy transfer through turns. The dynamic, time-tested templates support flowing direction changes and controlled carving suited to longboards, mid-lengths, and hybrid surfboards.

The side fins are designed for FCS tabs, while the center fin fits standard sliding center fin box installations used on most 2+1 surfboards.
