Freya Women's Sonic Underwire Sports Bra

D · Elevated

Lower PFAS concern for base fabrics, but no brand transparency on any specialty treatments applied.

Freya's Sonic Underwire Sports Bra is constructed from standard synthetic blends (nylon, elastane, polyester) common in athletic apparel. The brand does not publicly disclose whether any water-repellent coating (water-repellent coating), stretch-enhancing, or finish coatings contain PFAS.

Helps the grade

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
