Marmot Men's PreCip Evo Flex Rain Pants
Moderate PFAS concern, waterproof apparel typically uses fluorinated water-repellent coating; Marmot does not disclose chemistry.
The Marmot PreCip Evo Flex uses a water-repellent coating finish common in technical rain gear, which historically relies on PFAS-based treatments. Marmot has not publicly disclosed whether this product uses legacy fluorinated compounds or alternative chemistries. No independent lab testing or brand certification is publicly available.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
Safer alternatives in Rain Pants
Cotopaxi
Men's Salto Ripstop Pants
nylon ripstop fabric, no water-resistant coating mentioned
Lower-concern choice; ripstop nylon without explicit water-repellent coating treatment minimizes PFAS risk, but Cotopaxi's silence on materials leaves room for doubt.
⚠Risky category by default
Cotopaxi
Women's Subo Pants
Nylon ripstop (water-repellent coating-treated)
Lower-concern baseline; no waterproofing language confirms likely no intentional PFAS water-repellent coating, but brand is silent on chemicals.
⚠Risky category by default
Cotopaxi
Ambato Wide Leg Pant Women's
Nylon blend (primary), standard weave construction
Lower concern; standard apparel with no documented PFAS-prone features, but brand offers no transparency.
