Who’s behind it
Sourcing
Getting It
Cosiol is not a B Corp. The brand-level labels are thinner than the product-level ones.
Flagged in the sourcing ledger before you buy.
What the label won’t tell you
Cosiol is PFAS-free (verified). 24 of 24 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 24 styles from the store’s own product feed and publish a score only at full coverage. We read certificates, not adjectives.
And nothing is hidden: 1 was excluded. Every one is named in the sourcing ledger below.
Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 24 of 24 styles, thread by thread: 100% plant, 0% synthetic.
Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: No elastane.
Traceability on record: Country only; factory: Not disclosed for garment cut-and-sew (packaging: Poland; Pinatex finishing: Spain). 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. Cosiol is 100% plant fibre, so there is nothing to shed.
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.
Cosiol states it uses European Flax certified linen grown in Europe and OEKO-TEX Standard 100 Class 1 certified textiles, plus vegan Pinatex whose pineapple-leaf fibre originates in the Philippines and is finished in Spain. Cosiol produces its packaging in Poland but does not name the country, city or factory where its garments are cut and sewn. Cosiol names no spinning mill, weaving mill or dye house and publishes no supplier or factory list. Cosiol discloses material certifications and some processing countries but not its garment manufacturer.
How it was read: Every product listed in Cosiol's live catalogue is retrieved and its stated fibre composition read individually, from the Cosiol product page, Cosiol's own product data and its material labels. A fibre percentage for Cosiol is published only when 100% of the Cosiol catalogue has been read. Items Cosiol 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: These are the items Cosiol sells that carry no clothing textile to rate: gift cards, packaging and returns kits, jewellery, homeware, toys, body care and checkout line items. Cosiol's fibre percentage leaves them out rather than counting them as a pass or a fail.
