Why REI Co-op Trailgate Gear Bin Green 140 L grades highest here, and why that is not a pass

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 2 products it beats, so you can see exactly where the 45 points between the top and the bottom of this waterproof outdoor gear storage bags ranking come from. Nothing in this category reaches our 70 point pass mark, so this is the shape of the field rather than a recommendation.
