Airush Freewing Nitro

The Airush Freewing Nitro immediate responsiveness makes it feel like it has half a square meter more power. Starting at well under 1.5 kg, the ultra-lightweight is something you feel instantly.


The extra stiff struts create control and a wider wind range, so you can enjoy the wing in more wind conditions.
The key to the Nitro is the new Ho’okipa Ultra PE high pressure leading edge and strut, with our proven Ultra PE load frame.

Airush and Starboard have a combined 50 years of chasing responsiveness, lightweight and durability. Today, the Freewing Nitro is the best example of this yet.

Airush Freewing Nitro Features:


The HO’OKIPA Ultra PE fabric is 25% lighter than traditional Dacron leading edge materials. The reduced diameter structures and optimized details result in an overall weight saving of up to 30%.


Able to run 80 – 100% more leading edge pressure, creating a stiffer structure and ultimately allows for a thinner leading edge.


Utilizing the same Ultra PE primarily fiber as the leading edge and struts, the load frame carries much of the primarily load running through the canopy. This prevents the canopy cloth from overstretching and losing performance. This also increases responsiveness by creating a more locked in shaping into the canopy.


Thinner tips reduce the oscillation of the wing when the wing is in neutral.
This makes the Airush Freewing Nitro easier to control when the wing is flagged out.


The higher tension leading edge increases tension which improves the stability of the wing, low end-power and responsiveness.


Reduces the drag on the wing, when the wing is flagged out while riding or down winding.
This is especially important in more offshore wave conditions to help keep the rider on the wave face.
Allows a higher angle of attack when going upwind or traveling at higher speeds.


The biggest combined benefit of the Ultra PE is the ability to run higher pressure without sacrificing longevity.
This higher tension leading edge creates a much more responsive frame that can be loaded before jumping, pumps incredibly well and responds quickly to rider input.


The bag fits both the wing and the pump with ease. It also comes with carrying straps for your convenience.

*The pump is not included


The NITRO is available in both window and no Window versions.
The windowless version offers the lightest weight possible, however, windows may be required for competition.



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, to nd 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 ber (for their given weight) or had inconsistent strength and distribution throughout the fabric.

Ho’okipa 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 Ho’okipa Ultra PE is made up of 48% recycled content by weight.

Understanding Ultra PE

  • A super-strong ultra-high molecular weight polyethylene (UHMwPE) ber that offers maximum strength with minimum weight.
  • 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.
  • 15x stronger than steel at the same weight and 2x lighter than Carbon Fiber.
  • As well as its extraordinary strength, excels in cut and abrasion resistance and has a high resistance to UV.
  • Is so light that it floats on water.
  • Stiff does not mean fragile, 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 Airush Freewing 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.
