Tuff Sack Dry Bag vs Trailgate Gear Bin Green 140 L: which is safer?

Where these two actually differ

• We flag DWR coating composition (fluorinated vs. fluorine-free), PVC plasticizer leaching, Coating degradation over time and Off-gassing from DWR or adhesives on the NRS 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 NRS.
• The NRS is Vinyl tarpaulin or PVC with durable water repellent 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 NRS grade, at 45% confidence against 78%, because it discloses less.
