This is by far the most popular type. These wheels can spin 360 degrees, so bags can be smoothly scooted along beside you (as well as pulled behind you or pushed in front of you), which makes it easier to transport two suitcases. Spinner wheels used to get panned for durability as they had an annoying tendency to buckle and/or snap off, but manufacturers are solving that problem and spinner wheels are lighter and more durable than in the past.Rolling Luggage
The original rolling luggage featured inline-skate-type wheels, also called fixed wheels or roller wheels. Many frequent fliers prefer these fixed wheels to spinner wheels, saying they're more stable, and make a suitcase lighter, roomier and easier to pull. This type of wheel also tends to be more durable.Duffel Bags
These are a very popular option for travel -- and not just for outdoor adventurers. Many people love the roomy yet minimalist packing style that duffle bags allow, and appreciate the durability and the softer construction that helps them to fit in places where a traditional suitcase won't. We found duffel bags that are stylish and chic, as well as top choices for the backcountry hiker that will last a lifetime.Garment Bags
Our increasingly casual world has made garment bags less common than they used to be, but there are still plenty of people -- male and female -- who need to take a suit or dress with them when they travel. While many suitcases have built-in options for handling dressy clothes without wrinkling or creasing them, none do it quite as well as a dedicated garment bag.Luggage Sets
While many hard-core travelers eschew luggage sets, preferring instead to own a specific selection of bags for their various travel needs, luggage sets are still a great choice for those who either need to pack a lot of stuff and want their bags to match, or for less-frequent travelers who want to own a good variety of bags -- and want the discount that usually comes with buying them as a set.
