O.b Pro Comfort Super Plus 16 pad vs Sport Ultra Thin Regular Qwik Dry 72 Total Pads: which is safer?

Where these two actually differ

• We flag Microplastic shedding or degradation, Irritation or allergic sensitization from adhesive or synthetic fibers and Bacterial growth or contamination from prolonged moisture on the OB and not on the Playtex.
• We flag PFAS in waterproof coating, Skin sensitization or allergic contact dermatitis and Bacterial/fungal growth if damp on the Playtex and not on the OB.
• The OB is rayon/viscose, cotton, and gelling polymers where the Playtex is cellulose/rayon core with waterproof coating, 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 OB is the one to buy.
• We are less certain about the Playtex grade, at 45% confidence against 78%, because it discloses less.
