Men's Italian-Stretch Chino Pant vs Men's Signature Italian Hopsack Suit Pant: which is safer?

Where these two actually differ

• We flag Azo dye contamination and allergic sensitization and Microplastic shedding from elastane on the Banana Republic and not on the Banana Republic.
• We flag Azo dyes and heavy metals in synthetic dye components, Formaldehyde in fabric finishes (wrinkle-resistance, sizing), Antimony in polyester fiber component and Lead or cadmium in metal hardware (buttons, zippers, rivets) on the Banana Republic and not on the Banana Republic.
• The Banana Republic is cotton-elastane blend, no known durable water repellent finish where the Banana Republic is Italian hopsack wool blend, no DWR treatment specified, 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.
