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 .
  • We flag PFAS (per-fluorinated alkyl substances), Inhalation hazard from spray aerosol, Skin or eye irritation from direct contact and Fabric degradation or color change with repeated application on the and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the is proprietary stain and water repellent coating on fabric, 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 grade, at 35% confidence against 78%, because it discloses less.

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 →
