Discovery Dry Bag 20L vs Trailgate Gear Bin Green 140 L: which is safer?

Where these two actually differ

• We flag Fluorinated DWR coatings (PFAS family), PVC polymer degradation and plasticizer leaching, Coating off-gassing and VOC release and Microplastic shedding from coating wear on the Cascade Designs and not on the REI Co-op.
• We flag UV degradation and additive leaching, Microplastics from mechanical wear and Odor and volatile organic compounds from manufacturing on the REI Co-op and not on the Cascade Designs.
• The Cascade Designs is PVC or polymer fabric with waterproof coating, unspecified where the REI Co-op is Polypropylene storage bin, no water-resistant coating mentioned, 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 REI Co-op is the one to buy.
• We are less certain about the Cascade Designs grade, at 42% confidence against 78%, because it discloses less.
