Where these two actually differ
- We flag Spandex/elastane degradation and leaching and PFAS in water-repellent finishes (DWR) 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 swimsuit fabric, likely uncoated where the Patagonia is Nylon/polyester blend with elastane (standard swimwear), 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 →
