Jerome Cloetens about the Slick Concept Blue


Concept Blue products are our next step towards a better future and an additional element in our Save Our Playgrounds campaign. Our R&D Team is dedicated to design products with the latest materials that have the least environmental impact available on the market. To help protect our playgrounds, we are committed to examine what we are already doing while continuing to explore what can be done in the near future and decades ahead. A sustainable ethos drives everything we do, from selecting and sourcing raw materials for our products to the manufacturing process and the lifecycle of everything we create. Concept Blue is the next chapter.



Slick Concept Blue

For Duotone Wing & Foiling, our popular Slick wing is the start of our new Concept Blue range. This innovative line introduces new materials, propelling us further towards a greener and more sustainable future.

In the manufacturing process of the Slick Concept Blue, we're reducing water consumption and chemical use by introducing undyed fabric. This not only helps in environmental conservation but also maintains the stability and performance of the wing. The result is a sporty performance that enhances your ride experience.

Deployed materials are complemented by bio bladders, recycled plastic parts, and less printed graphics applications, to further reduce the impact on the environment.

»The Slick Concept Blue matches other models in performance and durability, with a dedicated focus on utilizing materials and exploring potential improvements for enhanced sustainability.«

— Max Panjank, Product Manager

The Duotone apparel collection is truly unique because of its use of undyed organic cotton in several models of the Concept Blue range. Undyed organic cotton is simply organic cotton that has not been dyed or treated with any chemicals or coloring agents. This natural, unprocessed cotton has a number of advantages over its dyed counterparts.

Firstly, undyed cotton is much better for the environment. The dyeing and finishing processes used in traditional textile manufacturing can be incredibly harmful, releasing toxic chemicals and pollutants into the air and water. By using undyed cotton, the Duotone collection is able to reduce its environmental impact and help protect the planet. Secondly, undyed cotton is incredibly soft and comfortable to wear. Unlike dyed cotton, which can sometimes feel stiff or rough, undyed cotton is free from any harsh chemicals or treatments, making it gentle on the skin. Moreover, because it has not been subjected to any harsh dyeing processes, undyed cotton is less likely to irritate sensitive skin. Finally, undyed cotton has a natural, earthy look that is perfect for the minimalist, understated aesthetic of the Duotone.
