I was looking for all kind of bags and came across this duffel bag which as per the website says its long lasting.

Purpose: I want something big which can be used for both (Sometimes carry on baggage and sometimes normal luggage). But not sure about duffel bags as a whole as I have used suitcases my whole life. Does it mess up the ironed clothes?
Also, let me know which are you using right now?
