PFAS score
Cotopaxi · Rain Pants
Cotopaxi Women's Subo Pants
Lower-concern baseline; no waterproofing language confirms likely no intentional PFAS water-repellent coating, but brand is silent on chemicals.
Cotopaxi's Subo Pants are lightweight nylon ripstop travel wear. The brand makes no claims about waterproofing or stain resistance, suggesting they lack a chemical water-repellent coating finish, the most common PFAS vector in apparel. Cotopaxi does not disclose PFAS avoidance, so ask them directly if you need certainty.

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.
