Onzie Women's High Rise Sparrow Athletic Leggings
Lower concern; basic athletic leggings with no known PFAS triggers, but brand discloses nothing about treatments.
Onzie's Sparrow leggings appear to be a standard nylon-spandex athletic knit with no public information linking the product to PFAS-intensive processes (no water-repellent coating claimed, no stain guard advertised). The brand does not publicly disclose PFAS policies or material sourcing.

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.
