3.6" + 7" 2+1 Fin Set – FCS compatible. Natural Pro Glass (3 fins)

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

The 3.6" + 7" 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" 4A center fin for primary hold and directional control, paired with 3.6" side fins that add rail stability and assist turning without excessive drag.

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

The natural fiberglass material reflects classic fin construction and maintains visual clarity in the water. The side fins are designed for FCS-compatible dual tab systems, while the center fin fits standard sliding center fin box installations used on most 2+1 surfboards.

What Pro Glass is and Why Surfers Prefer It

Side fins (often called side bites) can increase hold, control, and responsiveness. But they also change glide, trim feel, and the classic flow of a single fin.
