Patagonia Women's Bottom Turn Racerback Bikini Top is the clear pick. Gap Factory Babygap Swim Two-Piece carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag PFAS in DWR water-repellent finish, Azo dyes (if dark colorants used), Formaldehyde resins in fabric finishing and Microplastics from synthetic fiber shedding on the Gap and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Gap.
- The Gap is Polyester blend swim fabric with DWR water-repellent finish where the Patagonia is Nylon/polyester blend with elastane (standard swimwear), which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the Patagonia is the one to buy.
- We are less certain about the Gap 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 →
