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

Where these two actually differ

• We flag Azo dyes in polyester/nylon, Formaldehyde-releasing resins in fabric finish, Waterproof coating degradation and leaching and Volatile organic compounds (VOCs) from coating 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 Nylon or polyester with waterproof coating, type 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 Outdoor Products grade, at 45% confidence against 78%, because it discloses less.
