Where these two actually differ
- We flag Azo dyes and color-fastness, Microplastic shedding and Allergic sensitization or skin irritation from dyes or finishes 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/polyamide blend (ribbed knit swimsuit) 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: 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 →
