PFAS score
Point6 · Waterproof Hiking Socks
Core Extra Heavy Crew
Skip until Point6 discloses water-repellent coating chemistry, merino wool crew socks likely treated with fluorinated water repellent, but no brand transparency.
Point6's Core Extra Heavy Crew socks are merino-based performance crew socks marketed for durability and moisture control. The product almost certainly uses a water-repellent coating (water-repellent coating) finish typical of outdoor/technical socks, which historically relied on PFAS chemistry.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
