Where these two actually differ

  • We flag PFAS in DWR finish (non-PFAS-specific hazard reporting) and Coating degradation and microparticle shedding over time on the Dockers and not on the Levi's.
  • We flag Azo dyes and color fastness, Formaldehyde residues from finishing and Degradation and microfiber shedding on the Levi's and not on the Dockers.
  • The Dockers is cotton/polyester blend with durable water repellent (DWR) finish where the Levi's is 100% cotton denim, no disclosed water-resistant treatment, which is most of the difference in these two grades.
  • The gap is 45 points, wide enough that this is not a close call, and the Levi's is the one to buy.
  • We are less certain about the Dockers grade, at 45% confidence against 72%, because it discloses less.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
