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 Vuori.
- We flag Formaldehyde-releasing resins in fabric finishing, Azo dyes, Microfiber shedding from spandex degradation and Undisclosed DWR chemistry (likely fluorinated PFAS) on the Vuori and not on the Cotton On.
- The Cotton On is cotton where the Vuori is nylon/spandex blend, 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 →
