Lightweight Waterproof Nylon Travel Luggage Cases Customized Early suitcases were made of wood or other heavy materials. With the popularity of air travel, luggage materials tended to be lighter, hard plastic or cloth. Most of the models also have built-in small wheels, which can be easily pulled by levers.
