Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Whirlibird V Interchange Jacket: 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 Columbia.
• We flag PFAS in durable water repellent (DWR) coating, Azo dyes in polyester/nylon coloring, Antimony in polyester fiber and Formaldehyde resins in fabric finishing on the Columbia and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Columbia is polyester/nylon with durable water repellent (DWR) finish, 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 Columbia grade, at 35% confidence against 72%, because it discloses less.
