Mechanix Coldwork Waterproof Leather M-Pact Driver Gloves
Skip until waterproof treatment is disclosed, leather work gloves often use PFAS-based water-repellent coating.
Mechanix markets these as 'waterproof leather' but does not disclose the water-repellent coating chemistry. Waterproof leather work gloves commonly use PFAS-based water-repellent coating (water-repellent coating) treatments. Without brand transparency or third-party verification, the PFAS risk cannot be ruled out.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
