Bestseller, the multi-brand fashion company that owns Jack & Jones and JJXX, first began collaborating with Spinnova in 2020.

Since then, the partnership has resulted in several milestones, including the release of the first commercially available Spinnova products by Bestseller in October 2022.

Jack & Jones and JJXX sustainability coordinator Nanna Hansen said: “Working with Spinnova has allowed us to incorporate their wood-based fibre into this stylish co-ord set, showcasing a fusion of great design and forward-thinking innovation. This collaboration marks a proud milestone for Jack & Jones in pushing the boundaries of fashion.”

Jack & Jones has gone on to create collections with the largest production volume of Spinnova products to date, as well as designing official attire for Danish Olympic and Paralympic athletes using the fibre.

Spinnova senior commercial manager Pedro Brito said: “Collaborating with Bestseller on these new Jack & Jones styles is a great example of how innovation and sustainability can create real value for consumers. By integrating Spinnova fibre into fashion-forward designs, we’re proving that responsible choices don’t mean compromising on style. This collaboration reflects Bestseller’s genuine commitment to driving sustainable change in fashion, and we’re proud to be part of that journey.”

Spinnova fibre is made from renewable raw materials and can be used in both conventional and modern textile manufacturing processes, such as those employed for cotton.

The fibre is suitable for applications similar to cotton, including trousers, denim, overshirts, jackets, T-shirts, and accessories. It can also be used in insulation and composite products.

Recently, Brazilian apparel company Insider entered into a non-binding Letter of Intent with Spinnova to secure access to future volumes of Spinnova fibre.
