Where these two actually differ
- We flag DWR coating composition (PFAS-related unknown) and Nylon microfiber shedding during wear and wash on the Arc'teryx and not on the Patagonia.
- We flag DWR finish composition (unstated chemistry) and VOC off-gassing from fabric and finish on the Patagonia and not on the Arc'teryx.
- The Arc'teryx is Nylon ripstop with DWR finish (type unspecified) where the Patagonia is Nylon with DWR durable water repellent finish, 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 →
