Where these two actually differ

  • We flag PFAS in DWR finish, Formaldehyde in textile finishes and Microplastic shedding from synthetic fiber on the Patagonia and not on the Speedo.
  • The Patagonia is Nylon/polyamide with DWR (durable water-repellent) finish where the Speedo is Polyester/nylon blend (standard swimsuit fabric), 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 Speedo 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 →
