Where these two actually differ
- We flag Azo dyes and synthetic colorants, Antimicrobial finishes (unspecified) and Formaldehyde in fabric finishing on the Old Navy and not on the Puma.
- We flag Azo dyes and Formaldehyde resins (finishing agents) on the Puma and not on the Old Navy.
- Both carry a flag for Microplastic shedding, so neither choice avoids it.
- The Old Navy is polyester/nylon blend performance fabric where the Puma is Cotton/polyester blend socks, no waterproofing, 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 →
