This soft-sided bag has a nice solid bottom so it will stand up by itself.  It also has a zipper at the top so it will close.  The handle is solid and plenty long enough.  The material is heavy so it will last a long time.  The only down side is that you cannot collapse or fold it completely down - the bottom will always be rigid even though the bag itself will fold flat.  This is great for use, but lousy for storage.  You also have to be careful what you use it for.  It's great for clothing and groceries, but boxes to the post office or other solid items will cause it to tip one way or another.  I will get lots of use out of it, but use my solid-side rollers for anything structured.
