The 3.43" Upright Side Fins are designed to provide fast, controlled response through tight arcs and directional changes. The upright template reduces rake, encouraging quick pivot off the rail while maintaining sufficient base area for hold through turns.
Constructed from natural Pro Glass, these fins offer a balanced flex pattern suited to a wide range of conditions. They are intended for use as side fins in multi-fin setups where responsiveness and controlled release are required. Supplied as a matching set of two fins.
