Billabong Women's Rising Tide Demi Underwire Bikini Top

D · Elevated

Lower-concern choice, standard swimwear materials without known PFAS triggers, but Billabong offers no transparency.

This bikini top uses conventional nylon and elastane construction with no known water-repellent or stain-resistant finish that would typically require PFAS. Billabong does not disclose PFAS use or avoidance for this product. No third-party testing or verified PFAS-free claims are available, so confidence remains moderate rather than high.

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.
