PFAS score
Ultracor · Yoga Leggings
Ultracor Women's K Heart Sprinter Ultra High Leggings
Lower PFAS concern, basic stretch apparel with no known water-repellent coating treatment, but Ultracor hasn't disclosed chemical inputs.
Ultracor's leggings are nylon-spandex athletic wear without marketed water-resistant or stain-guard finishes, which are typical PFAS vectors in activewear. The brand makes no public claims about PFAS content or avoidance. No third-party testing or certifications are publicly available for this product.

Why this grade

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.
