20L Roll-Top DryBag Backpack vs Trailgate Gear Bin Green 140 L: which is safer?

Where these two actually differ

• We flag DWR coating degradation and particle shedding, Formaldehyde resins in fabric finishing, Synthetic dye migration under moisture and heat and Microplastics from nylon abrasion on the YakAttack 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 YakAttack.
• The YakAttack is Nylon roll-top with DWR 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 YakAttack grade, at 35% confidence against 78%, because it discloses less.
