Where these two actually differ

  • We flag Undisclosed fluorochemical or PFAS treatment, Skin sensitization or allergic contact dermatitis and Fragrance or dye reactions 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/synthetic layers with undisclosed water-resistant treatment 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 35% 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 →
