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 Lululemon.
- We flag Azo dyes and colorant heavy metals, Formaldehyde resin finishes, Elastic and spandex degradation and Fragrance allergens from finishes or softeners on the Lululemon and not on the Cotton On.
- The Cotton On is cotton where the Lululemon is Nylon/polyamide blend (Luxtreme or similar synthetic 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 →
