Our aluminum mast section with optimized stiffness to weight ratio is ideal for Kite foiling. The forgiving 55cm mast is suitable for skimming just above the water and easy recovery - ideal for learning to foil or for shallow waters. The 70cm mast is ideal for learning to kitefoil, and freeride foiling in shallow or flat water conditions. The 85cm mast increases overall ride performance in choppy conditions for a more controlled high-speed ride. Features GeoLock
