Girls' Uniform Polo Shirt Shirt by Gap vs Boys' School Uniform Short Sleeve Polo Shirt: which is safer?

Where these two actually differ

• We flag Azo dyes and heavy metals in synthetic dyes, Residual pesticides in cotton, Antimony in polyester content (if blended) and Microfiber shedding during wash on the Gap Kids and not on the Izod.
• We flag Azo dyes and color fastness, Formaldehyde in fabric finishes, Antimony in polyester and Microplastic shedding on the Izod and not on the Gap Kids.
• The Gap Kids is cotton/cotton blend polo shirt, untreated where the Izod is cotton/polyester blend, no stated coating, 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.
