Where these two actually differ
- We flag Azo dyes and Microfiber shedding on the Carhartt and not on the Nike.
- We flag Durable water-repellent (DWR) fluorochemical finish, Formaldehyde in dyes or finishing resins and Coating degradation and microplastic shedding over time on the Nike and not on the Carhartt.
- The Carhartt is 100% cotton jersey knit, untreated where the Nike is Polyester blend with Dri-FIT moisture-wicking finish, 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 Carhartt is the one to buy.
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 →
