Old Navy Kids School Uniform Polo Shirt
Lower concern, basic cotton polo with no water/stain treatment claims, but Old Navy provides no PFAS transparency.
Old Navy's kids polo is primarily cotton or cotton-blend, with no advertised water-repellent coating, stain-resist, or waterproof finishes, the typical sources of PFAS in apparel. The brand makes no public PFAS disclosures or claims.

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.
