Stance All Terrain Mid Wool Snow Socks
Lower concern, wool socks need no water-resistant coating, but brand transparency on synthetics would help.
Stance's wool snow socks are primarily natural fiber (wool) with synthetic reinforcement for durability. Unlike technical outerwear with water-repellent coating finishes, socks typically don't require fluorochemical water-repellent treatments.

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.
