Men's Cooling Performance Boxer Briefs vs Women's Air Tech Performance Brief Panties 6-Pack: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in finishes, Antimony in polyester fiber, Elastane degradation under heat or UV and Microfiber shedding on the Reebok and not on the Reebok.
• We flag Formaldehyde resins in fabric finishing, Azo dyes and Elastomer degradation (spandex breakdown) on the Reebok and not on the Reebok.
• The Reebok is Polyester, elastane blend where the Reebok is nylon, spandex, cotton blend, 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.
