Where these two actually differ
- We flag Azo dyes and color fastness, Formaldehyde in fabric finishes, Antimony in polyester and Microplastic shedding on the Izod and not on the Kaynee.
- We flag Azo dyes (colorfast dyes), Antimony in polyester (if blended) and VOC off-gassing from dyes or sizing on the Kaynee and not on the Izod.
- The Izod is cotton/polyester blend, no stated coating where the Kaynee is cotton/cotton blend button-down shirt, 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 →
