Men's Fox River Basecamp 2.0 Ankle Socks
Lower PFAS concern for a basic wool-blend sock with no waterproofing claims.
Fox River Basecamp 2.0 Ankle Socks are merino wool-based with no advertised water-repellent coating, water-resistant, or stain-resistant treatment, the typical vectors for PFAS in apparel. The brand makes no PFAS disclosure either way.

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.
