Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's KJUS Pro 3L 2.0 Jacket Blue: 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 DWR coating (fluorocarbon chemistry undisclosed), Polyester microfiber shedding and microplastics and Membrane delamination and chemical leaching on the Kjus and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Kjus is 3-layer membrane with DWR-treated outer shell, 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 40% confidence against 72%, because it discloses less.
