You will notice the durability in the fabric when you feel it. It also has a Teflon protectant and a vapor barrier added to it to maximize its protection and protect the contents of the bag. The four wheels on the uprights roll very silently and they are very smooth when you are push or pulling them along. Another great feature is the bottom handle that is easy to grab. This will give you a good grip when you are putting your luggage in an overhead compartment or in the trunk of your car.
