Allbirds Women's Intimates & Sleepwear Allbirds Trino Bralette
Lower-concern base materials, but brand silence on PFAS processing leaves a data gap.
Allbirds Trino Bralette uses primarily merino wool and recycled fibers, inherently lower-risk materials for PFAS. The brand does not market PFAS-free status or third-party verification 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.
