Where these two actually differ
- We flag Inhalation hazard from spray application and Coating degradation and reapplication frequency on the Jason Markk 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 Jason Markk.
- The Jason Markk is Canvas, suede, nylon, natural rubber where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
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 →
