PFAS score

Altura Dynamic Pants
Lower concern; standard athletic pants unlikely to need water treatment, but no brand disclosure.
Altura Dynamic Pants are standard nylon/polyester performance trousers with no published water-repellent or stain-resistant treatment. Altra makes no PFAS claims either way. The base fabric materials carry lower inherent PFAS risk, but lack of transparency about finishes leaves moderate uncertainty.

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.
