Reformation Rio One Piece Swimsuit | Blue | XL
Lower concern on PFAS risk, but Reformation's silence on treatment chemicals limits certainty.
This one-piece appears to be nylon, a base material without inherent PFAS concerns. However, swimwear often receives chlorine-resistant, color-lock, or stretch-recovery finishes that may employ PFAS-based water-repellent treatments.

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.
