All 86 activewear products PFAS Authority has graded score below its 70 point pass mark for PFAS and other toxins, as of October 2026.
The full ranking is below, best-graded first, with every score linking to the evidence behind it. Nothing here clears our buy threshold yet, so the least-concerning options come first.
Is activewear safe?
None of the 86 activewear products we graded come back low-concern on our screen. Our grades are model-based assessments built from published materials, ingredient lists, certifications and brand disclosures, not laboratory tests, so they say what we can evidence rather than that anything is safe.

The best non-toxic activewear, ranked by grade
Why Cotton On All Day Crew Tee Women grades highest here, and why that is not a pass
Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 1 product it beats, so you can see exactly where the 45 points between the top and the bottom of this activewear ranking come from. Nothing in this category reaches our 70 point pass mark, so this is the shape of the field rather than a recommendation.
