Who’s behind it
Sourcing
Getting It
Contact
Eva Cassis is not a B Corp. The brand-level labels are thinner than the product-level ones.
What the label won’t tell you
71 of 71 styles scanned: zero PFAS, zero formaldehyde.
“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 71 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 71 of 71 styles, thread by thread: 93% plant, 0% synthetic.
Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: No elastane.
Traceability on record: see ledger. 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. Eva Cassis 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.
Confirmed at the source
plant fibre across all 71 styles, read style by style from the live product feed. No sampling, no marketing page.

CHECK IT YOURSELF
What it costs per wear, who actually makes it, and how much the fabric sheds.
Cost per wear is the honest test behind "buy less, buy better": a £200 coat worn 300 times beats a £25 one worn 5 times. It rewards wearing what you own and choosing things built to last.
