Where these two actually differ

  • We flag Durable water repellent (DWR) coatings and PFAS, Sodium polyacrylate gel and skin irritation, Rayon production and environmental contamination residues and Fragrance or additive sensitivities on the Always and not on the OB.
  • 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 Always.
  • The Always is Cellulose/rayon core with synthetic polymer backsheet and absorbent gels; waterproof layers likely DWR-treated where the OB is rayon/viscose, cotton, and gelling polymers, 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 Always grade, at 42% confidence against 78%, because it discloses less.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
