Summersalt swimwear averages Good on our four-band scale. None of them clear our buy threshold. That is above 59% of the swimwear brands we grade.

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.
