There seems to be an abundance of suitcases, mostly roller or spinner types, which are made to an exact size to satisfy the common airline limit of 22 x 15 x 8 inches.
However, I am looking for a much lighter bag without wheels, telescoping handles or other hard parts so that it can be folded flat, while maximizing the space inside it when unfolded. I would be putting in it a small day back and other bag which I normally use as a personal item but am not allowed on some flights during my next journey.
Is there a duffel or similarly soft bag with almost 22 x 15 x 8 inches dimensions?
Searching online for carry-on bags yields tons of results but it is surprisingly hard to narrow down to those matching a specific size. Even Amazon allows one to filter bags by color but not dimensions which seems backwards to me in terms of priority.
