Where these two actually differ
- We flag Azo dyes and synthetic colorants, Heavy metals in pigments and Fragrance allergens or residual chemical odors on the Calvin Klein and not on the Reebok.
- We flag Formaldehyde-releasing resins, Azo dyes and dye allergens, Antimony (polyester catalyst residue) and Spandex degradation and microfiber shedding on the Reebok and not on the Calvin Klein.
- The Calvin Klein is Cotton-blend knit jersey, uncoated where the Reebok is polyester blend athletic knit, 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 →
