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 in fabric finishing, Azo dyes and heavy metal mordants and Elastane (polyurethane) degradation and fiber shedding on the Athleta and not on the Allbirds.
- The Allbirds is Organic cotton blend with TENCEL lyocell where the Athleta is cotton primary; elastane blend for fit, 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.
