Where these two actually differ

  • We flag Antimony (polyester catalyst residue) and Microfiber shedding when washed or worn on the Aerie and not on the Patagonia.
  • We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Aerie.
  • The Aerie is Nylon/polyester blend swimwear, no specified water-repellent coating where the Patagonia is Nylon/polyester blend with elastane (standard swimwear), which is most of the difference in these two grades.
  • The gap is 25 points, wide enough that this is not a close call, and the Patagonia is the one to buy.

Both products run through the same public rubric, which covers 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 →
