Woolrich, an American brand known for outerwear and clothing, has introduced a sustainable parka made using unique protein fibers created by Spiber, in collaboration with the Japanese sportswear brand Goldwin.

The classic 'Arctic Parka,' which Woolrich first launched in 1972 for workers on the Trans-Alaska pipeline, has been reimagined into the 'Future Arctic Parka.' This modern version utilizes Spiber's sustainable fiber and innovative materials, including insulation made from recycled and bio-derived materials from Japan.

Goldwin had previously launched a special collection using Spiber's remarkable fibers. They have been working together with Spiber since 2015 to develop advanced protein-based materials.

Spiber, based in Japan, has increased production of its brewed protein polymers at their manufacturing facility in Thailand. This expansion is aimed at making these unique materials more available in the market.

Woolrich has expressed that these brewed protein fibers represent their commitment to making a difference in a society heavily reliant on limited natural resources. They aim to guide society towards a more sustainable and environmentally-friendly future.
