Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Reserve GORE-TEX 2L 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 Burton.
• We flag Fluorinated water repellent coatings (DWR) and membrane PFAS, Formaldehyde resins in synthetic textiles, Azo dyes in colored fabrics and Coating and laminate degradation over time on the Burton and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Burton is GORE-TEX 2L membrane + 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 Burton grade, at 45% confidence against 72%, because it discloses less.
