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 PFAS in DWR coating and Microplastic shedding on the Saucony and not on the Calvin Klein.
- The Calvin Klein is Cotton-blend knit jersey, uncoated where the Saucony is Polyester blend with DWR treatment, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Calvin Klein is the one to buy.
- We are less certain about the Saucony grade, at 45% confidence against 78%, because it discloses less.
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 →
