Wonder Nation Boys School Uniform Pique Polo Shirt with Short Sleeves vs Boys Classic Fit Flat Front Pant: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in finishes, Azo dyes and colorfast concerns, Microplastics from polyester shedding and Coating degradation and fiber release on the Bienzle and not on the Dickies.
• 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 Bienzle.
• The Bienzle is pique cotton blend (likely cotton/polyester) where the Dickies is cotton/polyester blend, no special coatings, 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.
