X-15: It’s all about speed. Four all-new 2025 Carbon Reflex Foil Slalom shapes, covering minimum to extreme conditions:

The 2025 X-15 evolution sizes 75, 79, 85 & 89 push the boundaries of aerodynamic improvement. Specifically optimized for use with tiny low drag high speed foils, while enhancing early takeoff practicality. Thinner overall profiles reduce aero drag, and minimize side wind interference. Flatter deck profiles reduce roll, while refined rear strap stance improves high wind control, yet retains light wind efficiency. Maximize your speed potential.

Pure performance. Refined. And Redefined.
