Where these two actually differ

  • We flag Azo dyes and color fastness, Microplastic shedding, Elastic degradation and metal nickel content and Chlorine interaction and fabric wear 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 swimsuit fabric 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: 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 →
