Where these two actually differ

  • We flag Formaldehyde resins in fabric finishes, Antimony in polyester, Microfiber shedding during laundering and Skin sensitization from undisclosed chemical treatments on the Old Navy and not on the Puma.
  • We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Old Navy.
  • The Old Navy is Nylon/polyester blend with moisture-wicking treatment where the Puma is Cotton/polyester blend socks, no waterproofing, 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 Puma is the one to buy.
  • We are less certain about the Old Navy grade, at 45% confidence against 82%, 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 →
