Where these two actually differ
- We flag Fluorinated DWR compounds (PFAS) and Coating degradation and particulate release on the Mammut and not on the Patagonia.
- We flag Azo dyes and heavy metal pigments and Microplastic shedding during wash on the Patagonia and not on the Mammut.
- The Mammut is Nylon/polyester with DWR treatment (unspecified chemistry) where the Patagonia is Polyester fleece (recycled), which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
- We are less certain about the Mammut grade, at 45% confidence against 72%, 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 →
