Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's 2L GORE-TEX SWASH 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 Per- and polyfluoroalkyl substances (PFAS) in membrane and durable water-repellent (DWR) f, Microfiber shedding during washing and wear, Azo dyes in outer shell and lining fabrics and Membrane degradation and delamination 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 membrane laminate (fluoropolymer-based), 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.
