Freewing Nitro 2022

Couleur: Slate and Grey

 The Nitro Wing features cutting-edge designs with innovative materials to offer wingfoilers and wingsurfers a no-compromise, high-performance wing


This ultra-responsive, lightweight and super durable wing delivers instant, smooth power for wingfoiling and windsurfing. It feels like it’s 1m larger but controls like it’s 1m smaller, exactly like nothing else.

Introducing Hookipa Ultra PE – by Challenge Sailcloth

Developed in conjunction with Challenge Sailcloth, this unique woven composite is the result of exhaustive development and testing. It offers the optimum balance between responsiveness, lightweight and long-term performance.

Traditional Ultra PE materials relied on a high percentage of films, coatings or glues to stabilize the material. The outcome of this was that these materials were strong, but either needed complicated seam constructions, had a limited amount of structural (for their given weight) or had inconsistent strength and distribution throughout the fabric.

Hookipa Ultra PE takes a reliable woven structure and supercharges the material through the use of Ultra PE instead of traditional polyester fabric.

The high amount of material in the composite that is structural, has allowed us to optimize all areas of the construction, resulting in that beautiful blend of responsiveness, lightweight and durability.

Incredibly, the most high-performance fabric we have ever developed, comes with a reduced environmental impact, where Hookipa Ultra PE is made up of 48% recycled content by weight.

Understanding Ultra PE

  • Ultra PE Fiber is a super-strong ultra-high molecular weight polyethylene (UHMwPE) ber that offers maximum strength with minimum weight.
  •  Ultra PE has extremely long molecular chains that transfer load more effectively. So it‘s stronger at the same weight or lighter at the same strength than alternatives. In a direct comparison to polyester, it is up to 32x Stronger.
  •  Ultra PE fiber is 15x stronger than steel at the same weight and 2x lighter than Carbon Fiber.
  • As well as its extraordinary strength, Ultra PE excels in cut and abrasion resistance and has a high resistance to UV.
  •  Ultra PE fiber is so light that it floats on water.
  • Stiff does not mean fragile, Ultra PE also has very high ductility – It can absorb a lot
  • of energy before it breaks.

Understanding the characteristics of this material is the key to the responsiveness of the NITRO, the process if inflation places a higher tension on the fabric and you feel that immediately. This does not stop at the strut and leading edge but is integrated into the canopy through the Ultra PE load frame.
