Watertight Gear Expandable 40L White Dry Bag vs Trailgate Gear Bin Green 140 L: which is safer?

Where these two actually differ

• We flag Phthalate leaching (PVC plasticizer migration), Waterproof coating degradation and off-gassing and Microplastic shedding from coating wear on the Outdoor Products 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 Outdoor Products.
• The Outdoor Products is PVC or TPU dry bag with unspecified waterproof coating 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 Outdoor Products grade, at 35% confidence against 78%, because it discloses less.
