Fox River Men's Physical Trainer Lightweight Quarter Crew Socks (2 Pack)
Lower PFAS concern, plain athletic socks with no water/stain treatment claimed.
Fox River's lightweight quarter socks are standard synthetic-blend athletic wear with no disclosed waterproof, stain-resistant, or water-repellent coating finishes, the main drivers of PFAS in apparel. The brand makes no PFAS claims either way. Standard socks of this type carry lower PFAS risk than treated performance textiles.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
