If you're familiar with wet-weather brand Rains, it's probably because of this backpack. This bigger, beefier iteration of their classic model is made from the same completely waterproof rubbery material, with reinforced trimmings for even more protection. As far as pockets go, you're looking at a main interior compartment, a side-access laptop sleeve, and an easy-access zip pouch on the front. Other upgraded details here include metal hardware, a padded backside, a water-repellent zipper, a bike lock loop, and an adjustable belt that lets you stuff the bag all the way to the top.
