The quality of this bag was really bad.  The first (and only time) I used it, it ripped out 12" on both of the bottom seams--on the first leg of a three-stop trip.  Thank goodness I'd packed things inside a garbage bag inside this bag in order to keep them dry,otherwise I'd have had belongings falling out all over the place!  I had to duct tape the bag together to get my stuff home.  SUPER poor quality.  I've requested a refund, so hopefully that will go through fine.  But my advice is to avoid this bag and buy something that won't rip out the very first time you use it.
