Men's Dress Shirt Slim Fit Non Iron vs Men's Force Relaxed Fit Short-Sleeve Pocket T-Shirt: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in durable-press finish, Coating degradation and microfiber shedding and Chlorine bleach sensitivity in treated fabric on the Calvin Klein and not on the Carhartt.
• We flag Azo dyes and Microfiber shedding on the Carhartt and not on the Calvin Klein.
• The Calvin Klein is cotton blend with durable press/non-iron finish where the Carhartt is 100% cotton jersey knit, untreated, 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 Carhartt is the one to buy.
• We are less certain about the Calvin Klein grade, at 35% confidence against 78%, because it discloses less.
