Every grade below is built from published materials, ingredient lists, certifications and brand disclosures, scored on one public rubric and ranked best-graded first. Each score links to the full breakdown of what earned it, and the numbers across the whole dataset are published too.

Is synthetic athletic wear non-toxic?

None of the 15 synthetic athletic wear products we graded clear our screen. Non-toxic is not a defined or regulated term, so what we can tell you is what our graders recorded. Beyond PFAS, the hazards found or left unruled-out on synthetic athletic wear products in this category are microplastics, heavy metals, artificial dyes, formaldehyde.

Why Arc'teryx Men's Cormac Logo Shirt 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 synthetic athletic wear 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.

The synthetic athletic wear we would skip

Lowest scoring in this category, worst first, with the reason.

How to read these scores. PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Each grade is a model-based assessment built from published ingredient lists, materials, certifications, brand disclosures, recalls and third-party lab results where they exist. Read the full rubric to see exactly what adds and removes points.

What we check on synthetic athletic wear

  • Confirmed PFAS, PTFE or fluoropolymer content, which is the heaviest penalty we apply.
  • Stain, water or grease resistant treatments, which usually mean fluorinated chemistry.
  • Whether the brand discloses what is in the product, or stays silent behind a “clean” claim.
  • Independent lab results and certifications where they exist.
