Where these two actually differ

  • We flag PFAS in DWR (durable water repellent) finish, Formaldehyde resins in fabric finishing and Coating degradation and microplastic shedding on the Levi's and not on the Patagonia.
  • We flag Formaldehyde-based finishing resins and Dye bleed and skin contact allergens on the Patagonia and not on the Levi's.
  • The Levi's is cotton/polyester blend with moisture-wicking treatment where the Patagonia is cotton denim, no durable water repellent (DWR) coating, which is most of the difference in these two grades.
  • The gap is 70 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
  • We are less certain about the Levi's grade, at 45% confidence against 82%, because it discloses less.

Both products run through the same public rubric, which covers 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 →
