Where these two actually differ
- We flag DWR coating degradation and chemical release and Microplastic shedding from ripstop fabric on the Arc'teryx and not on the Patagonia.
- We flag DWR coating chemistry (unspecified replacement for PFAS), Nylon and polyester fiber shedding / microfiber release and Coating degradation over time on the Patagonia and not on the Arc'teryx.
- The Arc'teryx is Nylon/polyester ripstop with DWR coating (unspecified) where the Patagonia is Nylon/polyester blend with DWR (durable water repellent) treatment, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
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 →
