Where these two actually differ
- We flag Azo dyes and synthetic dye heavy metal content, Dye bleed and color fastness and Elastane (spandex) degradation and leaching on the Alo Yoga and not on the Patagonia.
- We flag Elastane (spandex) degradation under heat or chlorine on the Patagonia and not on the Alo Yoga.
- The Alo Yoga is Nylon/spandex blend (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 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 →
