Jackets & Coats Allbirds Full Zip Wool Blend Puffer Jacket Women Size Small vs Men's Backland Windstopper 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 Atomic.
• We flag DWR coating degradation and microparticle release, Formaldehyde resins in base fabric finishing, VOC off-gassing from multi-layer assembly and Membrane delamination and coating flaking on the Atomic and not on the Allbirds.
• The Allbirds is Wool blend with synthetic fill (likely polyester) where the Atomic is Windstopper membrane with DWR coating (likely polyester/nylon base), 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 Atomic grade, at 45% confidence against 72%, because it discloses less.
