Where these two actually differ
- We flag DWR treatment chemistry (PFAS status unverified) and Microplastic shedding from shell abrasion on the Patagonia and not on the Therm-a-Rest.
- We flag PFAS in DWR coating, Synthetic fiber shedding and microfiber release and Mold and bacterial growth if stored wet on the Therm-a-Rest and not on the Patagonia.
- The Patagonia is Down fill + nylon or polyester shell with DWR treatment where the Therm-a-Rest is Synthetic insulation + nylon shell with DWR 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 →
