Wigwam Cl2 Hiker Pro Low Socks
Lower-concern choice; Wigwam discloses no PFAS treatment, and Merino wool socks rarely require water-repellent coating coatings.
Wigwam's Cl2 Hiker Pro appears to be primarily Merino wool blend without advertised water-resistant or stain-resistant treatments that typically introduce PFAS. The brand makes no PFAS claims, neither positive nor negative, and no lab data is publicly available.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
