Men's Intense Power Sport Tee vs Men's Run Coolcell Cooling Running 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 Puma.
• We flag Formaldehyde or formaldehyde-releasers in fabric finishes, Azo dyes or heavy metals in dye pigments, Antimony in polyester fiber and Microfiber shedding during washing on the Puma and not on the Calvin Klein.
• The Calvin Klein is Cotton-blend knit jersey, uncoated where the Puma is polyester blend with moisture-wicking treatment, 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.
