Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Alto Light HS Hooded Jacket Men's: 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 fluorinated compounds (PFAS category; graded separately per your brief) and Microfiber shedding during use and washing on the Mammut and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Mammut is HS (Hybrid Shell) fabric with 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 Mammut grade, at 42% confidence against 72%, because it discloses less.
