All Birds Natural Leggins Xl Black

D · Elevated

Lower PFAS concern, natural materials without performance coatings, but brand transparency on PFAS is absent.

Allbirds' 'Natural Leggings' are made from natural fibers without explicit water-repellent coating or stain-resistant treatment, placing them in the lower-risk category for PFAS. However, Allbirds does not publicly disclose PFAS practices or hold independent certifications like MADE SAFE.

Helps the 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.
