Where these two actually differ
- We flag Azo dyes in synthetic colorants, Spandex degradation and microfiber shedding, Formaldehyde resins in fabric finishing and Allergen sensitization from dye or finish residuals 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/spandex blend swim fabric 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 →
