Under Armour Men's 6 Pack Performance Tech Crew Socks
Lower concern; standard athletic socks with no known PFAS-prone treatments, but no public commitment from brand.
Under Armour's Performance Tech crew socks are a polyester-nylon blend marketed for moisture-wicking and durability, not water-repellency or stain resistance, the main vectors for PFAS in apparel. The brand does not disclose PFAS use, treatment, or testing for this product.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 73% 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.
