Where these two actually differ
- We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Under Armour.
- We flag Azo dyes and heavy metals in dye pigments, Elastane (spandex) degradation and dermal irritation and Microplastic shedding during washing on the Under Armour and not on the Puma.
- The Puma is Cotton/polyester blend socks, no waterproofing where the Under Armour is Cotton blend with elastane, 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 →
