Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Firewall Mountain 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 Rab.
• We flag PTFE/fluorocarbon-based DWR coating (PFAS risk), Microplastic shedding from synthetic textiles, Formaldehyde resins in textile finishing and Azo dyes in synthetic fabrics on the Rab and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Rab is Nylon/polyester with DWR (durable water repellent) finish, 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 Rab grade, at 45% confidence against 72%, because it discloses less.
