Where these two actually differ
- We flag Azo dyes (reactive and direct dyes in gingham printing), Formaldehyde resins in fabric finishing, Heavy metal residues in dyes and pigments and Degradation and microfiber shedding over time on the J.Crew and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the J.Crew.
- The J.Crew is Cotton-blend gingham weave (likely cotton/polyester blend) 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, which covers 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 →
