Boys' School Uniform Short Sleeve Polo Shirt vs School Uniform Kids Short Sleeve Rapid Dry Polo 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 Lands' End.
• We flag PFAS in durable water-repellent and stain-resist finishes, Formaldehyde resins in dyes and finishes, Azo dyes (potential aromatic amine release) and Antimony in polyester fiber on the Lands' End and not on the Izod.
• The Izod is cotton/polyester blend, no stated coating where the Lands' End is polyester blend with DWR and stain-resist finish, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Izod is the one to buy.
• We are less certain about the Lands' End grade, at 35% confidence against 72%, because it discloses less.
