H&M · Swimwear
H&M Ladies Padded-Cup High-Leg Swimsuit
Moderate concern due to unspecified water-resistant treatment on swimwear; H&M's transparency on PFAS chemistry is weak.
Swimsuit fabrics commonly receive water-repellent coating (water-repellent coating) finishes that have historically contained PFAS, but H&M does not publicly disclose the treatment chemistry for this garment. The brand has not committed to PFAS-free manufacturing or published testing data.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
