Dragging heavy suitcases through increasingly large airports can be a royal pain in the rear — so why not let them drag themselves? That's exactly what PA Series Luggage ($1,370) was designed for. The cases are built using stress frame technology to provide added strength and reduce weight, and feature flat motor technology built right into the wheels. Additional features include an anti-gravity handle that puts 85% of the weight over the wheels, TSA-approved combination locks, force sensors and tilt switches, a Live Locator ID to help locate your suitcase if you happen to lose it, and an included, built-in umbrella. It's suitcase technology, evolved.
