Where these two actually differ

  • We flag PFAS in DWR finish, Azo dyes, Formaldehyde resins in finishes and Microfiber shedding from degraded DWR on the Dennis Uniform and not on the Dickies.
  • We flag Azo dyes and colorants, Heavy metals in dyes and pigments and Residual solvents or sizing agents on the Dickies and not on the Dennis Uniform.
  • Both carry a flag for Antimony in polyester, so neither choice avoids it.
  • The Dennis Uniform is polyester twill with unspecified DWR/stain finish where the Dickies is cotton/polyester blend, no special coatings, 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 Dickies is the one to buy.
  • We are less certain about the Dennis Uniform grade, at 45% confidence against 78%, because it discloses less.

Both products run through the same public rubric, which covers 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 →
