Old Navy Kids' School Uniform Jersey Polo Shirt vs Boys' School Uniform Short Sleeve Polo Shirt: which is safer?

Where these two actually differ

• We flag Azo dyes and excess dye residue and Microfiber shedding and microplastic persistence on the Bienzle 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 Bienzle.
• The Bienzle is cotton jersey knit 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.
