The spinner suitcase is the biggest luggage innovation since some savant attached a set of inline wheels to a standard suitcase and travelers the world over got rolling.
What distinguishes a spinner suitcase from
rolling duffel bags and big suitcases that roll is this: It has four wheels instead of two, easily spinning 360 degrees.
On a flat surface such as a long airport hallway, a spinner suitcase rolls like a dream. Aside from grabbing it off an airport baggage carousel, there's no heavy lifting or tilting involved -- so you can pack as much as your spinner suitcase will hold. These are some I like.

The corners are reinforced with a thick plastic that protects the four wheels. It has two zippered pockets on the front, a flat zippered pocket on the back, and can expand by 2.5" if you come back with more stuff than when you left. I also like that there's a cloth hook inside that you can use to hang garments on top of your other clothing, and then fold before zipping up the spinner. If you're planning to leave on a trip lasting up to two weeks, consider getting the larger
Liz Claiborne 29" Spinner Suitcase.

Roomy and expandable, it also features a large outside pocket and jaunty striped interior that thoughtfully includes a business card window just in case the spinner gets waylaid.

But make no mistake: With its multi-directional spinners, this suitcase is the latest thing on four wheels. For longer journeys, Samsonite also makes a
29" model.

Even if you get caught in a downpour, your packables won't get drenched. The only downside to choosing a hard spinner suitcase is that it's heavier than those made of lighter but less durable materials.

The three pieces are all constructed of durable polycarbonate and can expand up to 25% if you come home with more stuff than when you left.

Garment bags are especially useful when packing dresses and suits. And when they move as gracefully as a practiced couple taking their turn on the dance floor, you've got something special.
