I ordered two of these at the beginning of the school year for my 4th grade boys. The part that touches the ground when you pull it is made of fabric, so of course it was destroyed. Within three months the bottom of them was torn and ripped. The water bottle holder touches the ground when you pull, so they have holes and you can't keep a water bottle in them any more. We have very mild weather here so they are not being dragged through snow, salt or mud. These don't hold up to every day wear and tear well at all.
