Where these two actually differ
- We flag Elastane (spandex) degradation and leaching under heat on the Allbirds and not on the Athleta.
- We flag Formaldehyde resins (durable-press finishes), Azo dyes, Spandex degradation and microfiber shedding and Residual monomer and volatile organics on the Athleta and not on the Allbirds.
- The Allbirds is Organic cotton blend with TENCEL lyocell where the Athleta is Nylon, spandex blend (standard performance fabric), which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
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 →
