Always In Motion Boxer 5 vs Women's Air Tech Performance Brief Panties 6-Pack: which is safer?

Where these two actually differ

• We flag DWR finish chemical composition (PFAS/fluorinated repellents) and Elastane (spandex) degradation and microfiber shedding on the Lululemon 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 Lululemon.
• The Lululemon is nylon blend with DWR finish where the Reebok is nylon, spandex, cotton blend, 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 Reebok is the one to buy.
• We are less certain about the Lululemon grade, at 45% confidence against 72%, because it discloses less.
