Where these two actually differ
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Vitamin A.
- We flag Formaldehyde-releasing resins (finish/sizing), Microfiber shedding from synthetic fabric and Allergen contact dermatitis from dyes or finish on the Vitamin A and not on the Patagonia.
- The Patagonia is Nylon/polyester blend with elastane (standard swimwear) where the Vitamin A is Nylon/spandex blend swimsuit fabric, 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 →
