Where these two actually differ
- We flag PFAS in chlorine-resistant DWR coating, Synthetic fiber microfiber shedding and Elastic degradation and material leaching on the Lands' End and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Lands' End.
- The Lands' End is Nylon/polyester blend with chlorine-resistant treatment (DWR coating likely) where the Patagonia is Nylon/polyester blend with elastane (standard swimwear), 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 Lands' End grade, at 45% confidence against 72%, because it discloses less.
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 →
