Buck Mason Men's California Oxford Bd Shirt
Lower concern; untreated cotton oxford has minimal PFAS risk, but brand offers no transparency.
Buck Mason's California Oxford is a classic untreated cotton button-down with no apparent water-repellent or stain-resistant finish, the main source of PFAS in apparel. The brand does not disclose PFAS practices or hold relevant certifications.

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.
