Where these two actually differ
- We flag Inhalation exposure to volatile organic compounds (VOCs) and propellants, Residual coating contact with skin or mucous membranes and Environmental persistence and bioaccumulation via textile shedding on the Granger's and not on the Nikwax.
- We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Granger's.
- The Granger's is DWR-treated fabric coating (proprietary formula) where the Nikwax is wax-based waterproofing, 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 Nikwax is the one to buy.
- We are less certain about the Granger's 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 →
