Duffel bag verse a wheeled bag
The rolling suitcases first used by airline pilots are the inspiration for the many types of wheeled luggage now available for travelers. Your options for wheeled luggage can be broken down into two categories: wheeled luggage and duffels.
Durable luggage with wheels is an excellent choice for business travelers, or for recreational travelers who won't be carrying their luggage around on a daily basis. For example, the North Face Sidetrack 25 travel bag features an expandable main compartment for extra storage; handles on the top, bottom, and side, for easy retrieval from the baggage carousel; and a webbed strap to attach additional bags.
Remember that a hiking pack with wheels is not a good choice for backpacking trips, but backpacks or duffel bags with wheels can be useful for the casual traveler who won't be carrying the bag around all day. Wheeled duffel bags are lighter in weight than wheeled suitcases and contain many of the same organizational features. The Athalon 29-inch Over/Under duffel bag boasts a section that separates boots, laundry, or other items from the main compartment. It also features sealed in-line skate wheels for smooth handling.
