What the label won’t tell you
Kuyichi is PFAS-free (verified). 0 of 0 styles scanned: zero PFAS, zero formaldehyde, dye process on record: Low-impact / GOTS-certified dyes
“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 0 styles from the store’s own product feed and publish a score only at full coverage. We read certificates, not adjectives.
Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 0 of 0 styles, thread by thread: 51% plant, 49% synthetic.
Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: No elastane.
Traceability on record: Not disclosed; factory: Türkiye, Portugal, Pakistan, Tunisia, Italy, Spain, Austria. We publish the full sourcing chain and the honest red flags, including where sources conflict.
Synthetic underwear sheds plastic fibres onto your skin and into the water with every single wash. Kuyichi is 49% synthetic, so yes. These styles shed. Wash cool, use a guppy bag, and favour the plant-fibre options in the range.
Sources: consumer research on formaldehyde in easy-care fabrics (~9% of people react), PFAS in water- and stain-resistant finishes, and hypoallergenic underwear for eczema and contact dermatitis.

The complete clothing data behind the score
Where the materials come from, who makes it, and how traceable it is.
Kuyichi (founded by NGO Solidaridad) is a transparency pioneer: it publishes a full multi-tier supplier list on its website and on Open Supply Hub, links each product to the factory that made it, and has signed the Transparency Pledge. Since 2016 all its cotton is organic, recycled or regenerative, with organic cotton from the Akasya cooperative in Izmir, Türkiye, and named fabric mills (Bossa, Calik, Orta Anadolu, Candiani), dye/laundry houses and garment factories across Türkiye, Portugal, Pakistan and Tunisia, complete with worker counts and certifications. This is close to full farm-to-shelf traceability.
How it was read: Every product listed in Kuyichi's live catalogue is retrieved and its stated fibre composition read individually, from the Kuyichi product page, Kuyichi's own product data and its material labels. A fibre percentage for Kuyichi is published only when 100% of the Kuyichi catalogue has been read. Items Kuyichi sells that carry no clothing textile, such as gift cards, packaging, jewellery and homeware, are excluded from the percentage rather than counted as a pass or a fail.
Why excluded: Nothing was excluded: every item counted is a textile product.
