Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Stoney HS Thermo Hooded Ski 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 Mammut.
• We flag DWR coating composition (PFAS risk), Polyamide degradation under heat or UV and Microfiber shedding during washing on the Mammut and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Mammut is Polyamide outer with DWR finish (composition unspecified), 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 Mammut grade, at 45% confidence against 72%, because it discloses less.
