Women's Bottom Turn Racerback Bikini Top vs Women's Crossed-Back Seersucker Bikini Top: which is safer?
Patagonia Women's Bottom Turn Racerback Bikini Top is the clear pick. Tommy Hilfiger Women's Crossed-Back Seersucker Bikini Top carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Tommy Hilfiger.
- We flag Azo dyes and heavy metals in pigments, Formaldehyde in finishing resins, Microfiber shedding and Elastane degradation and leaching on the Tommy Hilfiger and not on the Patagonia.
- The Patagonia is Nylon/polyester blend with elastane (standard swimwear) where the Tommy Hilfiger is Seersucker cotton blend (typical, 100% cotton or cotton/polyester), 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 →
