Danner Men's N45 Mid GTX Waterproof Hiking Boots

F · High PFAS

Hiking boot with Gore-Tex and water-repellent coating, waterproof gear typically uses PFAS; no brand transparency on chemistry.

Danner's N45 Mid GTX uses Gore-Tex waterproof membrane and water-repellent coating (water-repellent coating) treatment on textiles, both common vectors for PFAS in outdoor footwear. Danner does not publicly disclose PFAS status or commit to PFAS-free formulations.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
