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 heavy-metal pigments in printed textiles, Elastane (spandex) degradation and microfiber shedding, Formaldehyde-based finishing resins in synthetic textiles and Skin irritation from dyes, optical brighteners, or residual processing chemicals on the Reiss and not on the Patagonia.
  • The Patagonia is Nylon/polyester blend with elastane (standard swimwear) where the Reiss is polyamide (nylon) or elastane blend 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 →
