Bigger and heavier than I thought.  With three different clunky metal zippers, it also makes a lot of noise any time you move.  It is heavy even when empty. I ordered the small, and it has plenty of room, if that is what you are looking for. It seems sturdy. But way too uncomfortable for me.  I was hoping to bring this with me for a short vacation.  I knew right away it was not what I needed.  Should've returned it, but ran out of time.
