This Manhattan Portage messenger bag is for high school or college kids who are tired of the same old backpacks, and prefer something fresh, urban, and, quite frankly, “cool.” What’s really great about this particular Manhattan Portage design (there are many others to choose from) is that by simply unzipping the surrounding zipper, the nylon bag doubles in size — enough to fit books, notebooks, etc. Like most bags, this one includes a variety of zippered and unzippered pockets (on the back of the bag, on the flap, beneath the flap and two in the main compartment), and comes in a variety of “teen-friendly” colors. Some moms will also love this as a diaper bag!
