Where these two actually differ

  • We flag Azo dyes and color fastness, Formaldehyde residues from finishing and Degradation and microfiber shedding on the Levi's and not on the Patagonia.
  • We flag PFAS in DWR (durable water repellent) coating and Degradation of finish over time on the Patagonia and not on the Levi's.
  • The Levi's is 100% cotton denim, no disclosed water-resistant treatment where the Patagonia is cotton/organic cotton denim, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.

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 →
