Where these two actually differ
- We flag Elastane (spandex) degradation and microfiber release, Antimony in polyester and Fragrance and dye allergens (contact dermatitis) on the Brooks 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 Brooks.
- The Brooks is nylon, polyester, elastane blend 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 →
