Guide to SLS construction on Duotone Surfboards.

 Duotone leads the way in 2021 Surf Kite construction with the "Innegra Shield."

The Duotone research and development team constantly seeks improvements in the construction of their kites, twintips, and Surfboards.
The real challenge for them is balancing the choice of materials to create a light, strong setup with the perfect flex for an ideal ride. 

The use of a cork deck as a shock absorber on Surf kites since 2018 has been validated by all riders. Other materials were tested, but they simply couldn't match the technical qualities of cork, so the results weren't satisfactory.

These experiments led Duotone to seek materials that could complement cork and replace fiberglass laminate.

With 20 years of experience using Innegra fabric as a shock absorber on high-end carbon Twin-Tips, Duotone decided to try it on their Wam, Whip, Fish, and Pro Session Surfboards as well.

Throughout the development process, which involved dozens of prototypes, Duotone kiteboarding discovered the many advantages of using Innegra fabric to replace certain fiberglass layers.

First, it's stronger than fiberglass at an equivalent weight. This results in significant weight reduction without making the board more fragile.

Additionally, this fabric provides more flex. This gives the boards a more forgiving feel. This is especially noticeable in the choppy conditions and rough waters we often encounter in kitesurf.    

Finally, because the material itself is less brittle than fiberglass, the Surfboards are stronger, particularly against impacts that could crack and shatter a fiberglass laminate.
Innegra simply flexes. It absorbs impacts, making the boards much less prone to dings and cracks.
This is why Duotone calls it the "Innegra Shield" because it truly protects the board from potential damage you might experience with a kite Surfboard.

Duotone has made the 2021 Kite Surfboards a little lighter, more durable, and with better flex.

All these characteristics make them high-performance and strong kitesurf boards.
