Where these two actually differ
- We flag Azo dyes and heavy metal colorants, Antimony in polyester, Microplastic shedding during wash and PFAS in Dri-FIT water-repellent finish (DWR) on the Nike and not on the Nike.
- The Nike is Nylon/polyester blend fabric, no waterproofing or stain treatment disclosed where the Nike is nylon/polyester blend with Dri-FIT moisture-wicking treatment, 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 Nike is the one to buy.
- We are less certain about the Nike grade, at 42% confidence against 72%, because it discloses less.
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 →
