Old Navy Kids School Uniform Jersey-Knit Polo Shirt 3-Pack
Lower concern for basic untreated cotton; Old Navy makes no PFAS claims, so verify care labels for any water-repellent coating finishes.
This is a plain-knit cotton polo with no stated water-repellent or stain-resistant treatment, which means lower PFAS risk compared to advanced-finish apparel. Old Navy does not publicly disclose PFAS practices, and cotton inherently does not require Teflon-type coating or Teflon-family coating.

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.
