Datasheet updated February 2026
The Ozone Fusion V2 Ultra-X is the most advanced wing foil wing ever designed for demanding competition and freerace. This wing is the result of Ozone's expertise in paragliders, ram-air kitesurf kites, and wingsuits. It features a patented 100% double-surface design with Ram Air technology and a full Aluula frame. Already the 2024 IWSA world champion, the Fusion V2 Ultra-X pushes the limits of speed, upwind performance, and control in wing foil.

THE FUSION V2 ULTRA-X IN ACTION
DETAILED DESCRIPTION
Patented double surface technology.
The Fusion V2 Ultra-X is the only wing foil wing in the world to use a 100% double surface design with Ram Air technology. Ozone's experience producing paragliders, foil kites, and wingsuits inspired this architecture. It creates a high-pressure area enclosed between the upper and lower surfaces. This results in a closed aerodynamic profile that eliminates turbulence generated under the Leading Edge of single-surface wings. The drag reduction is considerable, directly translating into top speed and upwind capability.
The internal rib structure supports both layers of fabric. It helps the wing smoothly manage dynamic pressure differentials as the angle of attack changes. For the V2, Ozone drew inspiration from the internal ribs of their R1 V5 Ram Air race kites. This optimizes pressure between the two surfaces, improving overall efficiency.
Aluula frame and Ultra-X construction.
The new full Aluula frame, including the Leading Edge and strut, allowed Ozone to reduce the Leading Edge diameter for even more aerodynamic performance. It still maintains superior rigidity. Ultra-X is Ozone's label for any product that pushes the boundaries of a specific discipline beyond industry standards.
The canopy uses a lightweight Teijin TechnoForce double ripstop fabric on the upper surface, contributing to overall weight reduction. The front and rear handles are made of carbon fiber with an EVA grip and an ergonomic profile. The elongated front handle lets you adjust pressure based on your position on the course and power level.
V2 evolutions compared to V1.
Ozone has retained the planform and concept of the Fusion V1, but the V2 has been completely redesigned with new materials. The internal ribs are lighter, and they increase internal pressure through improved airflow. Mini-ribs on the Trailing Edge offer a tighter, more responsive profile.
We've significantly improved maneuverability. This makes both your **transfers** and jibes easier and quicker to initiate. The **profile** has been updated for better performance at the bottom of the **wind range**, all while maintaining excellent control and speed at the top. New race windows ensure optimal visibility.
Settings and use.
Adjusting the Variable Leech Line Tension via the pigtails at the wingtips lets you fine-tune the wing's behavior. A tight leech line gives you more power in the low end and a fuller **profile**. A loose leech line delivers more speed and control in the high end.
Controlling the Fusion requires a slight technical adjustment. The rule is simple: let the wing fly. When pumping, short movements are sufficient. When riding, focus on the front handle to promote acceleration. The wing naturally accelerates upwind without the instability of single-surface wings. Good trim is essential, and the Fusion does the rest.

construction details
key features
Aerodynamics
Double Surface and Ram Air: Redesigned internal ribs reduce weight while increasing pressure between the two surfaces. Combined with mini-ribs on the Trailing Edge and optimized air intake valves near the Leading Edge, the double surface profile is tighter and stronger than ever.
Optimized Tip Junction: To maintain smooth aerodynamics, the last upper and lower panels separate to connect to the top and bottom points of the Leading Edge tube.
drainage and drying
Drainage Holes: Four holes on the Trailing Edge (two near the strut, two on the tips) quickly drain any water that gets between the surfaces.
Non-Stick Bottom Surface: This makes handling the wing faster when you're out of the water.
Accelerated Drying: Lighter materials mean faster drying after your session.
handles and control
Ergonomic Carbon Handles: Angled for maximum comfort and control. The extended front handle lets you adjust pressure based on your position on the course. The grips feature finger ridges.
Harness Line: Pre-attached to the handles, you can easily remove it if needed.
safety and accessories
Swivel Leash: This Dyneema line features an elastic core and a stainless steel swivel to prevent tangles. It connects via a loop on the Leading Edge.
Padded Belt: The Waist Padded Belt with a sliding hook lets you crank upwind and ride longer without sacrificing mobility.
Technical Compression Bag: Fold the wing in sections and clip it into the bag for optimal protection of the Ultra-X materials.

FAQ - Ozone Fusion V2 Ultra-X
The Fusion V2 Ultra-X is the only wing foil wing to use a 100% double surface design with Ram Air technology. Unlike single surface wings, where air creates turbulence under the Leading Edge, the enclosed double surface creates a pressurized aerodynamic profile. This drastically reduces drag. The result is significantly higher top speed and upwind performance.
Yes, it also appeals to experienced freeriders who seek the sensation of speed and maximum efficiency. Steering requires a slight adjustment period (prioritize the front handle, short pumping), but the performance gains are accessible to any advanced intermediate rider.
Aluula is both lighter and stiffer than Dacron. This increased stiffness allowed Ozone to reduce the diameter of the Leading Edge, improving aerodynamics. The result is a wing that is approximately 20% lighter, with more direct feedback and better responsiveness.
Yes. Ozone manufactures each wing to order in its factory and offers full color customization (center and tips). Contact us with your color choices or your Ozone color code, and we will place the exact order. Manufacturing time is approximately 30 days.
For an 80 kg rider, recommended sizes range from 4m (strong wind, 20+ knots) to 7.3m (light wind, 10-15 knots). In competition, it's common to go up a size to capitalize on the wing's power and efficiency, as its improved maneuverability helps conserve energy during a long race day.
Yes, it is officially registered for IWSA World Cup and Formula racing competitions. It already secured the top two places in the 2024 IWSA Wingfoil Racing World Championship in its first season with the V1.
