Billabong Women's Tanlines Demi Underwire Bikini Top
Lower concern, standard swimwear fabric with no known PFAS triggers, but brand provides no explicit transparency.
This bikini top is made from conventional nylon/polyamide swimwear material, not a category typically treated with PFAS durable water repellents (water-repellent coating). Billabong makes no public PFAS claims or disclosures for this product. No third-party certifications, lab data, or recalls found.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
