Boys' School Uniform Short Sleeve Polo Shirt vs French Toast Boys Short Sleeve Pique Polo: which is safer?

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 School Apparel.
• We flag Azo dyes and heavy metals in colorants, Formaldehyde in finishing resins, Dye bleed and skin contact irritation and Allergens in dyes and finishes on the School Apparel and not on the Izod.
• The Izod is cotton/polyester blend, no stated coating where the School Apparel is Cotton pique knit, 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.
