Men's Intense Power Sport Tee vs Men's Dri-FIT Ready Fitness T-Shirt: 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 Nike.
• We flag Antimony in polyester fiber, Formaldehyde in textile resins, Volatile organic compounds (VOCs) from finish coating and Microplastic shedding from fiber degradation on the Nike and not on the Calvin Klein.
• The Calvin Klein is Cotton-blend knit jersey, uncoated where the Nike is polyester blend with Dri-FIT moisture-wicking 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.
