Mephisto Lifestyle For Adventure Gore-tex Hiking Boots Brown Nubuck Sz
Gore-Tex waterproofing carries PFAS risk; Mephisto makes no PFAS disclosure.
These boots use Gore-Tex, a Teflon-family coating membrane historically treated with PFAS-based water-repellent coating (water-repellent coating) finishes. Mephisto does not publicly disclose PFAS presence, absence, or commitments. The nubuck leather may also receive stain/water treatments of unknown composition.

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.
