F-ONE is proud to unveil the new QuadX Composite, its newest generation of laminated material.

Built around an exclusive four-layer architecture and our innovative “Inside Film” concept, the QuadX places the PET film at the core of the structure between two fabrics, rather than on the outside like other traditional composites.
Ultra-PE fabric
5 times more resistant to tear and elongation than the best Dacron.
X-pattern Ultra-PE fibers
Precisely angled fibers that stabilize the fabric on the bias.
PET Film
Controls deformations in all directions, remains flexible yet efficient, and, being placed inside, is protected from external stress, preventing delamination and cracking.
Outer polyester fabric
Protects the whole structure and reinforces all assembly seams.

Optimized to perform in all directions (warp, weft, and bias), the QuadX Composite delivers greater strength, responsiveness, comfort and durability, while remaining lightweight at only 125 g/m². Its robustness reduces the need for reinforcement seams during assembly, making production easier and lowering the final weight of the sail.

Featured on some of our upcoming wing and kite models, the QuadX Composite is built to keep its shape, its feel, and its performance session after session.
