OK I know that it is a backpack.  My point being, it holds a lot, has really good manufacturing and material, is easy to carry and easy to open and close.  We just went on a weekend trip (2 of us, 2 nights) and everything fit into the one bag.  Am I saying that it is the only great bag out there?  No but in this case I think you get what you pay for, and don't forget the life time warranty.
