Triarchy is not a B Corp. The brand-level labels are thinner than the product-level ones.
What the label won’t tell you
0 of 0 styles scanned: zero PFAS, zero formaldehyde.
“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: 98% plant, 2% 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. Triarchy is 2% 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.
Confirmed at the source
plant fibre across all 29 styles, read style by style from the live product feed. No sampling, no marketing page.
On record. Cotton certification not documented. Flagged in the ledger.
Not named publicly. Factory certifications not documented. See the sourcing ledger.
Low-impact finishes. Chemical flags and dye chemistry are recorded for every brand we scan.
Plastic-free. Compostable or plastic-free packaging verified against the brand's own record.
Every certifier this brand claims, with a direct link to the proof where it exists, or flagged where it is only the brand’s word.
