The Greenough 4-A Single Fin is the most iconic, functional and versatile single fin available, because it works extremely well on just about every type of surfboard. The 4-A has been True Ames' bread and butter for over 40 years now, and it is still the most popular single fin design there is due to it's all-around and well-balanced performance.
 
These Volan fins are fine-tuned with precision foils as well as proper flex. Crafted with a labor of love, these fins undergo the strictest quality control. Our Volan panels are meticulously hand-laid and templated ensuring optimal weave orientation and superior strength, with flex coming more from the body rather than just the tip. This enhances speed and projection off the bottom and through turns, making our Volan fins a pinnacle of the highest performance flex characteristics.
