I have purchased two of these backpacks and after 20-30 days of use both of them had holes on the bottom. The seams were falling apart. I have purchased additional warranty as well. When I called Overstock.com I was told, that they will reimburse me for shipping, warranty and the merchandise. Since I was happy with that response, I went and purchased new backpacks from Overstock.com. (More expensive ones too)..... Finally, I received e-mail from them that they will credit my account.... So, I called them... AND, what a different story. NO REIMBURSEMENT ON THE SHIPPING AND NO REIMBURSEMENT ON WARRANTY. I have recommended Overstock.com to so many friends, and they have purchased things from them as well. Now, I will have to tell them about my experience. THEY TELL YOU ONE THING, BUT DO ANOTHER THING.
