Sweaty Betty Power Piping Workout Leggings
Moderate concern: athletic leggings with moisture-wicking coating likely treated with legacy or undisclosed water-repellent coating agent; Sweaty Betty silent on PFAS.
Sweaty Betty Power Piping leggings use synthetic fabrics with water-resistant finishes typical of performance activewear. The brand makes no public disclosure about PFAS in treatments.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 58% 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.
