Women's Bottom Turn Racerback Bikini Top vs Women's Nadine Halterneck Pleat-Detail Swimsuit: which is safer?

Where these two actually differ

• We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Reiss.
• We flag Azo dyes and synthetic colorants in nylon/polyester, Microplastic shedding from degraded synthetic fibers, Residual formaldehyde or formaldehyde releasers in finishing resins and Degradation of elastane/spandex under chlorine and UV on the Reiss and not on the Patagonia.
• The Patagonia is Nylon/polyester blend with elastane (standard swimwear) where the Reiss is Nylon/polyester blend with likely DWR finish, 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 Reiss grade, at 45% confidence against 72%, because it discloses less.
