In terms of material, wheeled travel bags are usually made of wear-resistant and waterproof fabrics to ensure they can withstand tests in complex travel environments. In addition, some high-end wheeled travel bags also pay attention to detail handling, such as the comfort of the handle and the smoothness of the zipper, to improve the user experience.

The main feature of a wheeled travel bag is its roller design. The material of the rollers is mostly rubber, which has good wear resistance and shock absorption effect, making the travel bag smoother and less noisy during the dragging process. According to the type of roller, wheeled travel bags can be divided into one-way wheels and universal wheels. Unidirectional wheels, also known as built-in rollers, have the advantage of being durable and able to withstand rough handling during transportation. However, their disadvantage is that they cannot change direction arbitrarily, making them more suitable for use on complex road surfaces such as towns, train stations, and bus stations. The universal wheel can roll in any direction, and its advantage is that it can freely change direction with the movement of the body during walking, but its disadvantage is that it may not withstand rough loading and unloading during transportation, making it more suitable for use on smooth roads in high-end shopping malls and airports.

Wheeled travel bag, a design that combines convenience and practicality, brings great convenience to travelers' itinerary. This type of travel bag is usually equipped with rollers and pull rods, making it easy to carry heavy objects on smooth roads.

Travel bags also carry our travel memories and stories. Every time we travel, we pack different items into our travel bags, which witness our travel experiences and also record our growth and changes. Travel bags have become our loyal companions during our travels, accompanying us through exciting journeys one after another.
