GORE-TEX Rain Pants
Known PFAS-containing technology; GORE-TEX has not committed to PFAS-free alternatives.
GORE-TEX rain pants use expanded Teflon-type coating (a Teflon-family coating) as the core waterproof membrane, a well-documented PFAS-containing material. While GORE-TEX does not publicly disclose PFAS content or commit to phase-out, the ePTFE membrane is integral to the product's breathability and waterproofing.

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.
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.
⚠Risky category by default
