Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Rival Insulated 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 Spyder.
• We flag DWR coating (PFAS status unknown), Polyester fiber degradation and microfiber shedding and Adhesive or glue off-gassing from seam tape or bonding on the Spyder and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Spyder is Polyester shell with DWR treatment; synthetic insulation, 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 Spyder grade, at 45% confidence against 72%, because it discloses less.
