Where these two actually differ

  • We flag Azo dyes and colorant migration, Formaldehyde in finishing resins, Antimony in polyester and Skin irritation from synthetic fibers on the Fruit of the Loom and not on the Reebok.
  • We flag Formaldehyde resins in fabric finishing, Azo dyes and Elastomer degradation (spandex breakdown) on the Reebok and not on the Fruit of the Loom.
  • The Fruit of the Loom is polyester, elastane blend (mesh) where the Reebok is nylon, spandex, cotton blend, 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 →
