PX Invisible Backpack

It's not really invisible. But it does have a knack for making your stuff disappear. Thanks to a series of separated compartments, the PX Invisible Backpack lets you haul everything from a 15" laptop to a pair of shoes without looking like you're packed for a whole weekend. It's built from rugged, waterproof 1000D nylon, and sports rubberized zippers on openings that are most exposed — the main, laptop, and front compartments — while reversing those that are more out of the way.
