Surfers, it's time to upgrade your ride! This bohally 3-piece fin set gives you everything you need to transform your board's performance. Made from high-quality nylon plastic reinforced with glass fiber, these fins deliver the perfect balance of strength and flexibility. The fiberglass construction means they can handle some serious action while maintaining that responsive feel you want when carving waves. Measuring 4.3 inches at the base and 5.8 inches in depth (that's 109mm x 148mm for the metric folks), these medium-sized fins work great for most standard surfboards. The package includes the fin key and 6 screws you need for easy installation - no extra trips to the surf shop required! What we love about these fins is how they make your board feel neutral and free in the water while still providing excellent stability and control when you need it most. Whether you're catching your first waves or you're a seasoned surfer looking for reliable replacement fins, this set delivers solid performance without breaking the bank. Better control, smoother turns, and more fun in the water - what's not to love?
