Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Hydra Thermagraph 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 686.
• We flag Formaldehyde releasers in finishing resins, Flame retardant additives in coating or face cloth, Azo dye migration or carcinogenic dye residue and Membrane coating degradation and microparticle inhalation on the 686 and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the 686 is Polyester with waterproof/breathable membrane coating (Thermagraph), 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 686 grade, at 42% confidence against 72%, because it discloses less.
