Bioworks Corporation has announced the incorporation of its PlaX plant-based synthetic fibre in outerwear collections from The North Face and Neutralworks, under the Goldwin portfolio in Japan.

As a commercially viable alternative to synthetic performance fibres, PlaX has been rigorously tested, refined and validated for high-quality apparel applications over a three-year development period.

Based on a proprietary technology for modifying polylactic acid derived from renewable resources such as sugarcane, PlaX has been engineered to meet the demanding functional and aesthetic standards of premium outdoor and wellness brands.

Compared with conventional polyester, PlaX reduces CO2 emissions by approximately 70% in filament production and 50% in staple fibre production. Water consumption from raw materials processing through to yarn manufacture is reduced by around 90% when measured against cotton and in addition, PlaX biodegrades into water and CO2 under industrial composting conditions and is compatible with emerging chemical recycling processes.

The collaboration between Bioworks and Goldwin began in 2022 and has focused intensively on overcoming the traditional limitations of bio-based fibres, particularly in relation to dyeability, durability and long-term wear performance. Through repeated prototyping and close coordination with textile mills and dyeing facilities, the partners have optimised yarn processing conditions and fabric design to ensure the fibre can integrate seamlessly into commercial production without compromising quality or brand positioning .

PlaX is now available in commercial products including the Extreme Pile Hoodie Jacket from The North Face and the Snowmelt Full Zip Fleece from Neutralworks, both positioned within premium price segments. This sends a clear signal that sustainability can now be aligned with performance, aesthetics and consumer expectations at scale, rather than existing as a compromise or marketing add-on.

Goldwin’s adoption of PlaX reflects a broader strategic shift within the outdoor and lifestyle sector towards materials that reduce environmental impact without undermining technical performance, says Bioworks, which will continue to focus on combining material science with product design to support sustainable manufacturing and reduce lifecycle impacts.
