PFAS score
Altra · Hiking Pants
Ultra Pants
Lower concern for standard athletic wear, but Altra makes no public PFAS commitment.
Altra Ultra Pants are synthetic athletic wear with no known water-repellent or stain-resistant coating disclosed. Standard polyester/nylon apparel poses lower PFAS risk than treated water-repellent coating performance gear. However, Altra has not published transparency on PFAS use or sourcing, leaving some 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.
