If you're familiar with wet-weather brand Rains, it's probably because of their backpacks. This is the biggest, beefiest iteration of their classic model, 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 with a laptop sleeve and multiple easy-acces zip pockets, plus a mesh water bottle pocket and a front bungee-cord pocket. Other upgraded details here include metal hardware, padded straps, two tough webbing handles — and of course, a water-repellent zipper.
