Where these two actually differ
- We flag PFAS in water-resistant coating, Elastane (spandex) microfiber shedding, Coating degradation and leachables over use and Sensitization to treatment chemicals on the Athleta and not on the Speedo.
- The Athleta is Nylon/spandex blend with water-resistant treatment 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.
- We are less certain about the Athleta grade, at 45% confidence against 72%, 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 →
