Sustainability is no longer a buzzword in the apparel industry — it’s a requirement. For activewear brands looking to build an eco-conscious supply chain, two certifications dominate the conversation: GRS (Global Recycled Standard) and GOTS (Global Organic Textile Standard).
But which one is right for your sportswear line? Let’s compare.
What is GRS (Global Recycled Standard)?
The Global Recycled Standard is an international, voluntary certification that verifies the recycled content in a product and ensures responsible social, environmental, and chemical practices throughout the supply chain.
Key GRS Requirements:
- Minimum 50% recycled content to certify a product (20% for “contains recycled” claims)
- Traceability from recycled material source to finished product
- Environmental management (waste water treatment, air emissions)
- Social compliance (ILO labor standards, fair wages, no child labor)
- Restricted chemical use aligned with ZDHC (Zero Discharge of Hazardous Chemicals)
Common GRS Fabrics in Activewear:
- Recycled Polyester (rPET) — Made from post-consumer plastic bottles or post-industrial waste. Used in leggings, sports bras, and jackets.
- Recycled Nylon — Often sourced from fishing nets and fabric scraps. Excellent for swimwear and compression wear.
- Recycled Cotton — Pre- or post-consumer cotton waste. Less common in performance activewear.
Best for: Performance activewear, technical fabrics, and brands emphasizing recycled materials and circular economy.
What is GOTS (Global Organic Textile Standard)?
The Global Organic Textile Standard is the world’s leading standard for organic textiles. It covers the entire production process — from harvesting of raw materials to manufacturing, labeling, and distribution.
Key GOTS Requirements:
- Minimum 70% organic natural fibers for “made with organic” label; 95%+ for “organic” label
- No GMOs, synthetic pesticides, or synthetic fertilizers in fiber production
- Prohibited chemicals include formaldehyde, heavy metals, phthalates, and AZO dyes
- Strict wastewater treatment requirements at all processing stages
- Social compliance audits (same as GRS: ILO standards, fair wages, safe working conditions)
- Technical quality criteria (dimensional stability, colorfastness, abrasion resistance)
Common GOTS Fabrics in Activewear:
- Organic Cotton — Soft, breathable, and chemical-free. Great for yoga wear, t-shirts, and casual activewear.
- Organic Hemp — High durability and moisture-wicking properties. Emerging in outdoor and hiking apparel.
- Organic Bamboo (mechanically processed) — Smooth, silky hand feel. However, chemically processed bamboo does NOT qualify for GOTS.
Best for: Natural-fiber activewear, yoga wear, and brands that prioritize organic agriculture and chemical-free production.
Key Differences: GRS vs GOTS
| Aspect | GRS | GOTS |
|---|---|---|
| Focus | Recycled content & supply chain | Organic natural fibers & chemical processing |
| Fiber type | Recycled (synthetic or natural) | Organic natural fibers |
| Min. content | 50% recycled for certified label | 70-95% organic for staged labeling |
| Chemical restrictions | Yes (aligned with ZDHC) | Yes (stricter — comprehensive prohibited list) |
| Social criteria | Yes (ILO-based) | Yes (ILO-based) |
| Technical quality | Optional | Required (dim. stability, colorfastness) |
| Best for | Synthetic performance fabrics | Natural fiber garments |
| Certification cost | Moderate | Higher (more audits, stricter criteria) |
Which Certification Should You Choose?
Choose GRS if:
- Your activewear line uses synthetic fabrics (polyester, nylon, elastane)
- You want to highlight recycled content (e.g., “Made from 100% recycled polyester”)
- You’re targeting sportswear retailers that prioritize circular economy and plastic waste reduction
- Your products require high-performance stretch, moisture-wicking, and durability
Choose GOTS if:
- Your line uses natural fibers (cotton, hemp, linen)
- You’re targeting yoga and wellness brands that value organic materials
- You want the highest standard for chemical-free textile processing
- Your brand messaging revolves around organic farming and sustainability
Best of both worlds:
Many activewear brands now use GRS-certified recycled polyester for performance pieces (leggings, sports bras, jackets) and GOTS-certified organic cotton for lifestyle pieces (hoodies, joggers, t-shirts). Both certifications can coexist in your product line.
At GoSportLand, we offer both GRS and GOTS-certified manufacturing options, giving you the flexibility to build the sustainable supply chain your brand needs.
Why Certifications Matter in Activewear Sourcing
- Consumer trust — 67% of consumers consider sustainable materials important when purchasing apparel (McKinsey 2023).
- Retail buyers expect it — Major retailers increasingly require certifications for their supply chains.
- Greenwashing protection — Third-party certification is the only way to legally substantiate sustainability claims.
- Premium pricing — Certified sustainable products command 15-30% higher retail prices.
FAQ
Can a fabric be both GRS and GOTS certified?
No. GRS covers recycled content (usually synthetic), while GOTS covers organic natural fibers. A fabric can’t be both simultaneously. However, a blended fabric (e.g., recycled polyester + organic cotton) can carry both certifications if each component is certified separately.
Does GRS or GOTS certification increase production costs?
Yes — expect 10-25% higher fabric cost. However, the premium narrows as production scales. The cost can be partially offset by marketing the certification to customers willing to pay more for sustainable products.
Which is better for yoga wear?
For high-performance yoga leggings: GRS recycled polyester/nylon provides the best stretch and recovery. For relaxed yoga wear (hoodies, joggers, t-shirts): GOTS organic cotton is ideal. Many premium yoga brands use both.
