The idea is intriguing: Hang a set of shelves in your closet or on a door, fold and stow everything you'll need for a trip, and then collapse the shelf into your carry-on suitcase. When you get to your destination, simply open up your suitcase and pull the shelf open to its full height, then hang it in a closet or on a door. That's the premise behind Rise Gear's Riser Shelving. Three roomy shelves plus a shoe storage area and built-in laundry hamper simplify the entire packing process.

Having a hard time picturing it? Here's a video of our test:

Price and Where to Buy It: $79 from RiseGear.com. How it Rates

• Usefulness: 8/10. These shelves save time and increase efficiency: There's no unpacking at a destination, and no repacking if you're going city to city. And if you're in a place with limited storage, you're covered.
• Value: 7/10. At about $79, it's not cheap enough to be an impulse purchase for most people. If you think of it as a way to upgrade existing luggage, it improves the value equation significantly.
• Portability: 9/10. The shelves collapse easily into the main suitcase compartment, and store flat when you're not using them. The only downside is that they add a bit of weight to your bag, so if an ultra-light bag is your top priority, they may not be a good fit.
• Cool Factor: 10/10. To arrive at a destination, zip open a suitcase, and reveal an already organized and neatly folded mini-closet—that's cool.

Final Verdict: As long as you're not concerned about adding an extra 3 pounds (about the weight of a regular pair of shoes) to your bag, this is a great way to start organized and stay organized on the road. Rise Gear also makes suitcases (rollers, sliders, and weekenders) with built-in expandable shelves.
