This collapsible bag is absolutely wonderful. The main body material is light, flexible and durable. The bag can be easily stacked on a cabin bag or regular suitcase for easier transport on the roll. The fact that it is foldable makes it very easy to take with you in the suitcase as an extra bag if you want to buy and bring something back home with you or even just to use it on excursions and the like. This duffel is also great to use in everyday life as a gym bag or even as a bag for storage necessities in the car or otherwise.
