Classic Fit Solid Poplin No Iron Point Collar Dress Shirt vs Men's Farrier's Work Shirt: which is safer?

Where these two actually differ

• We flag Formaldehyde-releasing resins and Coating or finish degradation and leachables on the Arrow and not on the Patagonia.
• We flag Formaldehyde releasers in durable-press resins and Chemical off-gassing or skin irritation from finish residues on the Patagonia and not on the Arrow.
• The Arrow is cotton poplin with stain/wrinkle-resistant finish where the Patagonia is Organic cotton, standard construction, which is most of the difference in these two grades.
• The gap is 50 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
• We are less certain about the Arrow grade, at 45% confidence against 72%, because it discloses less.
