Where these two actually differ

  • We flag Formaldehyde resins in finishing, Spandex degradation and microfiber shedding and Skin irritation from dyes or residual chemicals on the Lululemon and not on the Puma.
  • We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Lululemon.
  • The Lululemon is Nylon/spandex blend, no water-repellent treatment 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: 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 →
