AYA (Eco Aya) is a mixed bag for non-toxicity: 50.4% of its range is plant fibre that breathes and biodegrades, with 0.0% plastic-based synthetics that can shed microplastics. Certifications: AYA (Eco Aya) does NOT hold whole-product third-party certifications such as GOTS, OEKO-TEX, Fair Trade, B Corp, or European Flax, and openly acknowledges this: its sustainability page states “we are aware that certificates do not ensure complete sustainability and non-toxicity.” Instead it references certifications at the component level: its Pima cotton is said to be farmed “according to USDA and GOTS standards” (a standards claim, not a held certificate), fabric finishing is described as “OEKO-TEX certified,” and inner labels are printed with “GOTS certified ink.” The Fashion Globe investigation notes AYA lists these component-by-component (which OEKO-TEX warns against in consumer communications) and that no certificate numbers appear on the site, preventing independent verification. AYA is also a member of the Plastic Pollution Coalition (a membership, not a certification). Specific European Flax, Fair Trade and B Corp status: Not publicly documented (no evidence AYA holds any)..
