Where these two actually differ
- We flag DWR chemical residue (PFAS status unknown), Azo dyes in polyester component, Formaldehyde in synthetic fiber processing and Microfiber shedding during washing on the Lspace and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Lspace.
- The Lspace is Nylon/polyester blend with DWR treatment 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 Lspace grade, at 45% confidence against 72%, because it discloses less.
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 →
