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 Saucony.
  • We flag Azo dyes and residual colorants, Formaldehyde resins (finishing agents), Antimony in polyester fiber and Microfiber shedding during wear and washing on the Saucony and not on the Calvin Klein.
  • The Calvin Klein is Cotton-blend knit jersey, uncoated where the Saucony is polyester mesh singlet, 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 →
