Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Jackets & Coats Nwt Allbirds Trino Puffer Women's Charcoal Size Small: which is safer?

Where these two actually differ

• We flag Durable Water Repellent (DWR) coating composition, Synthetic fill microplastic shedding and Coating degradation and leachables from synthetic lining on the Allbirds and not on the Allbirds.
• We flag PFAS in DWR coating, Coating degradation and leaching, Formaldehyde resins in finishing and Polyester microfiber shedding on the Allbirds and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Allbirds is Synthetic puffer insulation with unknown DWR coating, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Allbirds is the one to buy.
• We are less certain about the Allbirds grade, at 45% confidence against 72%, because it discloses less.
