Patagonia Men's Wild Idea Work Boots
Patagonia's sustainability reputation suggests care, but lack of PFAS transparency on work boots leaves moderate uncertainty.
Patagonia does not publicly disclose PFAS treatment details for these work boots. Work boots typically receive water-repellent (water-repellent coating) coatings that historically contained PFAS, though many brands have begun transitioning away.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 58% 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.
