Men's Ultimate Shirt vs Slim Fit Dress Shirt Men’s Large White Stretch Performance: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in finish, Microplastics shedding and Allergenic dyes or finishes on the Dockers and not on the Reebok.
• We flag Formaldehyde-releasing resins in finishes, Elastane/spandex degradation and microfiber shedding and Chemical residues from moisture-wicking treatment on the Reebok and not on the Dockers.
• Both carry a flag for Azo dyes and synthetic colorants, so neither choice avoids it.
• The Dockers is Cotton and polyester blend where the Reebok is polyester/cotton blend with stretch performance treatment, 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 Dockers is the one to buy.
• We are less certain about the Reebok grade, at 45% confidence against 72%, because it discloses less.
