Decathlon Review, Is Decathlon Non-Toxic?
Decathlon averages 28 out of 100 on PFAS Authority's PFAS and toxin screen across the 22 Decathlon products graded as of October 2026, and 2 of them reach its 70 point pass mark.
Decathlon grades Poor 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.
