What the label won’t tell you

The questions sensitive skin actually asks, answered

64 of 64 styles scanned, no sampling 90% plant · 9% synthetic ✓ read from the live product feed, not the marketing page
Are there hidden chemicals against my skin?

64 of 64 styles scanned: zero PFAS, zero formaldehyde.

Is "sustainable" just greenwashing?

“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 64 styles from the store’s own product feed and publish a score only at full coverage. We read certificates, not adjectives.

Is "100% cotton"
actually
100% cotton?

Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 64 of 64 styles, thread by thread: 90% plant, 9% synthetic.

Will the elastic bring me out in a rash?

Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: Elastane. Spandex, flagged red in the Skin-Safe section above.

Where's it really made,
and by whom?
Named farm and factory
GOTS chain of custodyTraceable back to the cotton

Traceability on record: see ledger. We publish the full sourcing chain and the honest red flags, including where sources conflict.

Am I shedding microplastics onto my body?

Synthetic underwear sheds plastic fibres onto your skin and into the water with every single wash. Kule is 9% 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.
