Boys' School Uniform Short Sleeve Polo Shirt vs Men's L.L.Bean Comfort Stretch Long Sleeve Oxford Shirt: 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 L.L.Bean.
• We flag Azo dyes and heavy metals in colorants, Formaldehyde resins in wrinkle resistance or sizing, Degradation of elastane over time and Allergenic or irritant dyes and finishes on the L.L.Bean and not on the Izod.
• The Izod is cotton/polyester blend, no stated coating where the L.L.Bean is Cotton blend with elastane, no stated finish, 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.
