On my trips to Asia, I bought some travel items that can transform into different forms, but I think you can find them online too.
I have a JanSport Driver 8 backpack that has skate wheels and shoulder straps that can be hidden.
You can roll it, hold it, or wear it on your back.
I also have a pair of jeans that can be turned inside out, so it’s like having two pairs in one.
