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 Zella.
- We flag Azo dyes in black textile, Spandex polymer degradation under heat or UV and Microfiber shedding during washing on the Zella and not on the Cotton On.
- The Cotton On is cotton where the Zella is Nylon/spandex blend, no stated treatment, 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: 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 →
