Where these two actually differ
- We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Tarrago.
- We flag PFAS in water-repellent nano-coatings, Respiratory exposure during application and Fabric discoloration or texture change on the Tarrago and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the Tarrago is Proprietary nano-coating on textiles, 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 Tarrago grade, at 35% 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 →
