Short version: Use GRS-certified recycled nylon or rPET, keep the certification chain documented, and only make claims you can prove. OEKO-TEX Standard 100 covers safe chemistry; GRS covers recycled content.
What "recycled activewear" actually means
Most eco activewear uses recycled nylon (from fishing nets / fabric waste) or rPET (from plastic bottles), blended with spandex. It performs like virgin fabric with a lower footprint — when the recycled content is certified.
The certifications that matter
- GRS (Global Recycled Standard): verifies recycled content and the supply chain. The key one for "recycled" claims.
- OEKO-TEX Standard 100: tests for harmful substances — safe-to-wear chemistry.
- BSCI: social / ethical factory audit.
Yesseam is BSCI audited and works with GRS and OEKO-TEX Standard 100 certified materials.
How to avoid greenwashing
- Only claim what you can document (ask for transaction certificates).
- Be specific: "made with 78% GRS-certified recycled nylon", not "eco".
- Don't imply the whole brand is sustainable if one style is.
Does sustainable cost more?
Recycled fabrics are usually a small premium over virgin, often offset by the higher price customers will pay for a credible eco story. Minimums can be slightly higher for certified custom colors.
