I am obsessed with my bag, and it has been what I’ve been looking for for years. The one simple thing that it needs is a strap to carry it on your shoulder, whether it be an additional shoulder strap, or a way to extend the handles so that it fits on your shoulder. It’s very difficult to carry up and downstairs when it is full. It is very heavy when a bag the size has items in it to carry it up and downstairs and places that you are unable to roll it.
