Where these two actually differ
- We flag DWR chemistry (PFAS or alternative) unverified, Nylon microplastic shedding (abrasion) and Degradation and leachate from aging DWR on the Patagonia and not on the REI Co-op.
- We flag UV degradation and additive leaching, Microplastics from mechanical wear and Odor and volatile organic compounds from manufacturing on the REI Co-op and not on the Patagonia.
- The Patagonia is nylon ripstop with DWR finish where the REI Co-op is Polypropylene storage bin, no water-resistant coating mentioned, which is most of the difference in these two grades.
- We are less certain about the Patagonia grade, at 45% confidence against 78%, 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 →
