Men's Farrier's Work Shirt vs Men's Slim Fit Non-Iron Dress Shirt: which is safer?

Where these two actually differ

• 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 Tommy Hilfiger.
• We flag Formaldehyde-releasing resin in non-iron finish, PFAS in water and stain repellent coatings and Finish degradation and microfiber shedding on the Tommy Hilfiger and not on the Patagonia.
• The Patagonia is Organic cotton, standard construction where the Tommy Hilfiger is Cotton/polyester blend with non-iron finish (likely resin treatment), which is most of the difference in these two grades.
• The gap is 70 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
• We are less certain about the Tommy Hilfiger grade, at 45% confidence against 72%, because it discloses less.
