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 Izod.
- We flag Azo dyes and color fastness, Formaldehyde in fabric finishes and Microplastic shedding on the Izod 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 Izod is cotton/polyester blend, no stated coating, 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 Izod is the one to buy.
- We are less certain about the Dennis Uniform grade, at 45% 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 →
