Where these two actually differ
- We flag Azo dyes and azo metabolites and Heavy metals in synthetic dyes (lead, cadmium, chromium) on the Cotton On and not on the Nike.
- We flag Formaldehyde-based finishing resins, Azo dyes and heavy metal pigments, Microplastic shedding and Allergic reaction to residual dyes or finishes on the Nike and not on the Cotton On.
- The Cotton On is cotton where the Nike is Nylon/polyester blend, no documented waterproof or stain-resistant coating, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
