Danner Men's Hot Weather TFX Drymax Crew Socks
Lower concern; no evidence of PFAS treatment in standard performance socks.
Drymax Drymax crew socks are performance athletic socks made from acrylic, nylon, and polyester. The brand makes no public claims about PFAS, and the product materials, moisture-wicking synthetics without noted water-repellent or stain-resistant finishes, carry lower typical PFAS risk than treated apparel.

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.
