lululemon Leggings Women's Wunder Train High-Rise Tight 28
High-performance leggings carry PFAS risk via water-repellent coating; Lululemon discloses nothing, skip until transparency improves.
Lululemon's Wunder Train leggings use nylon-polyester with water/sweat-repellent finishes typical of athletic wear. The brand does not publicly disclose PFAS use, testing, or water-repellent coating chemistry. No third-party PFAS certifications are held.

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.
