Boys Classic Fit Flat Front Pant vs Girls' Uniform Polo Shirt Shirt by Gap: which is safer?

Where these two actually differ

• We flag Azo dyes and colorants, Antimony in polyester, Heavy metals in dyes and pigments and Residual solvents or sizing agents on the Dickies and not on the Gap Kids.
• 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 Dickies.
• The Dickies is cotton/polyester blend, no special coatings where the Gap Kids is cotton/cotton blend polo shirt, untreated, 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.
