Women's The Amalfi Swim Dress vs Women's Bottom Turn Racerback Bikini Top: which is safer?
Patagonia Women's Bottom Turn Racerback Bikini Top is the clear pick. Andie Women's The Amalfi Swim Dress carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Durable water-repellent (DWR) coating chemistry, Microplastic shedding, Synthetic dye and finishing chemical residues and DWR coating degradation and reactivation products on the Andie and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Andie.
- The Andie is Nylon/polyester blend with DWR water-repellent treatment 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 Andie 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 →
