Mighty Good Basics 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: 95% plant, 5% synthetic.
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.
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. Mighty Good Basics is 5% 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.
