The John John Florence Scimitar Vapor Core thruster is designed for performance surfing in small waves. John rides this fin when he needs to generate speed when the waves are small and lack power. These fins feature a full Vector foil, helping enhance lift and generate speed. The Scimitar Tip is represented by the cut-off portion of the fin, tailoring the grip characteristics. Vapor Core is the lightest performance fin construction ever, consisting of a hollow core. Every single fin is handmade from start to finish at our HQ in Huntington Beach, CA, using aerospace grade materials.
