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 Respiratory irritation from spray/aerosol inhalation, Skin sensitization from direct contact, Undisclosed chemical composition (including PFAS uncertainty) and Residual product buildup on fabric and laundering contamination on the and not on the Nikwax.
- The Nikwax is wax-based waterproofing where the is Proprietary fabric protector coating, composition unspecified, 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.
