Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Kjus Insulated Storm 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 Kjus.
• We flag PFAS in DWR coating (fluorine-based water repellent), Coating degradation and microplastic shedding and VOC off-gassing from insulation or adhesives on the Kjus and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Kjus is Synthetic insulation + unspecified water-repellent 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 Kjus grade, at 45% confidence against 72%, because it discloses less.
