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 Azo dyes and processing residues, Spandex degradation products (from heat or sweat) and Microplastic shedding from wear and washing on the Nike and not on the Cotton On.
- The Cotton On is cotton where the Nike is Polyester blend (nylon/spandex mix), 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 →
