The HP Business Nylon Backpack offers a sturdy, all-purpose backpack for mobile professionals and students alike. Constructed from durable nylon, with extra padding in the back and shoulder straps, it is designed with comfort in mind. A foam padded handle also makes it easy to lift or carry. Plenty of room is available for materials and books in the three zippered sections, plus an external slot for a cell phone or PDA. Easily transport a notebook up to 17.3", or store a mini or thin and light notebook up to 12.1" inside a neoprene built-in pocket. And just for fun, the headphone pass-through slot ensures access to an MP3 player you can also store inside.
