Men's Intense Power Sport Tee vs Women's Sleeveless Training Tank Top: 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 Reebok.
• We flag Azo dyes and heavy metal dye residues, Formaldehyde in textile finish resins, Spandex (elastane) degradation and microfiber release and Fragrance or finishing chemical allergens on the Reebok and not on the Calvin Klein.
• The Calvin Klein is Cotton-blend knit jersey, uncoated where the Reebok is polyester blend fabric, no special coating, 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.
