(The Gear Loop) - Last year, Adidas announced a technical partnership with Finnish textile material company Spinnova, a specialist in alternative and recyclable textile materials for the garment industry, to create more sustainable leisure and activewear.

Eight months into the collaboration and Adidas is ready to reveal its Terrex HS mid-layer, which is designed for hikers and walkers, but is fashioned from 25 per cent wood-based fibres and 75 per cent organic cotton, ridding the top of any plastics.

The unisex mid-layer is a piece of multi-functional gear that works on the trails and then rolls up into its hood for easy storage or to create a pillow on longer adventures. A minimum of 25 per cent of the fabric uses wood-based fibres that are mechanically ground down to avoid the use of harmful chemicals. Working with the material’s natural colour and without using any dying or bleaching chemicals, the Terrex HS also uses less water than the standard dyeing process.

"Spinnova is on a mission to transform the raw material base of the global textile industry by providing radically sustainable and high-performance textile materials. We are very proud of the revolutionary results our teams have accomplished together," says Spinnova’s CEO and co-founder Janne Poranen.

Adidas says that by 2025, nine out of ten Adidas garments will carry a more sustainable technology, material, design, or method of manufacturing, whether that’s using recycled materials, materials from nature (in this case) or materials that can easily be made into a new product.
