Mammut Stoney HS Jacket Men's
Skip or contact brand for PFAS commitment; Gore-Tex traditionally uses PFFE but Mammut hasn't confirmed their water-repellent coating approach.
The Mammut Stoney HS uses Gore-Tex, a laminate membrane historically based on Teflon-type coating (a PFAS), though Gore has made some moves toward alternatives. Mammut makes no public PFAS disclosure for this jacket.

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.
