A curated portfolio of responsible trims, threads and accessory materials developed for real-world apparel production.
Sustainability without compromise on performance or commercial viability.
Designed NOT as a concept range, but as a practical pathway for brands seeking to improve trim-level material choices while maintaining performance, scalability and sourcing confidence.
Built for adoption, not demonstration.
Trims often determine whether garments can be disassembled or recycled. While brands have advanced fabric selection, threads, elastics, and labels can introduce incompatible inputs—creating friction in circular design and end-of-life recovery without solving cost or performance.
Innovation Partners
Made for durability, designed in partnership for responsibility.
The Responsible Trims Collection brings together Next-Generation Recycled Materials, Advanced Regenerated Inputs and Select Biodegradable Solutions.
Textile-to-Textile Recycling
Textile-to-textile recycled material innovation
A next-generation regenerated polyester made from end-of-life textile waste using molecular regeneration technology - designed to replace virgin polyester with less than half the associated CO2 emissions*, while maintaining performance and integrating into existing supply chains.
Advanced Polymer Recycling
Industrial-scale textile-to-textile material capability
Indorama Ventures contributes established recycled polyester capability, giving brands access to commercially credible solutions backed by scale and manufacturing relevance.
Designing Circular Materials
Biodegradable polymer innovation designed for real-world adoption
A drop-in alternative to polyester combining biodegradability, PET recyclability, performance parity and industrial scalability. Validated by OceanSafe at >93% marine biodegradation in 99 days, with no persistent microplastics and no heavy metals such as antimony. The material holds Cradle to Cradle Certified® Material Health Gold certification.
Jiaren
Commercial recycled material supply
Jiarun adds further recycled material capability to the collection, supporting broader sourcing flexibility and scalable product application.
Manufacturing & operations that meet commercial reality
Responsible materials only scale when they meet global manufacturing requirements. This collection is produced within Harnest's vertically integrated system, where material innovation meets industrial infrastructure for volume production and cost discipline.
As a vertically integrated manufacturing partner, Harnest can support:
