Men's Intense Power Sport Tee vs Men's Light Weight Quick Dry Moisture Wicking Top with 40+ UPF Protection: which is safer?

Where these two actually differ

• We flag Azo dyes and synthetic colorants, Heavy metals in pigments and Fragrance allergens or residual chemical odors on the Calvin Klein and not on the Calvin Klein.
• We flag Undisclosed DWR coating chemistry (likely PFAS or fluorinated alternatives), Formaldehyde or formaldehyde-releasing finishes (wrinkle/shrink resistance) and Volatile organic compound (VOC) off-gassing from synthetic blend and treatments on the Calvin Klein and not on the Calvin Klein.
• The Calvin Klein is Cotton-blend knit jersey, uncoated where the Calvin Klein is Synthetic blend with moisture-wicking and UPF 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 Calvin Klein is the one to buy.
• We are less certain about the Calvin Klein grade, at 45% confidence against 78%, because it discloses less.
