Sockwell · Waterproof Hiking Socks
Sockwell Men's Trail Blazer Moderate Compression Socks
Lower PFAS concern; standard compression socks without water-repellent finish.
Sockwell's Trail Blazer socks are primarily merino wool and synthetics without marketed waterproofing or stain resistance, which are typical PFAS application areas. The brand makes no PFAS claims and no public disclosure; standard socks carry lower intrinsic 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.
