Certain Dri grades Excellent on our four-band scale. On disclosure, the brand says nothing publicly about PFAS. See what every brand has published about PFAS for how that compares.

PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
