The introduction marks the culmination of a three-year joint development effort. Since 2022, Bioworks and Goldwin have collaborated to refine PlaX for performance outerwear, focusing particularly on dyeability, durability and the specific requirements of pile fleece. Extensive prototyping, yarn-processing adjustments and testing with textile and dyeing partners were required to meet Goldwin’s product standards.

The outcome is the new PlaX Boa Fleece, now commercially available and receiving strong early response, according to both companies.

Bioworks states that PlaX’s bio-based origin and improved processing performance position it as a lower-impact alternative to conventional synthetic fibres. By expanding its adoption, Bioworks aims to help reduce the environmental footprint of the fashion industry and support a more circular materials economy.

Both companies plan to continue their collaboration on material innovation and product design, with the intent to accelerate the broader use of plant-based synthetics in performance apparel.
