The whole "a great warranty is just marketing hooey" argument doesn't go anywhere with me. If a company is going to take the financial risk of a "no matter what" warranty, they will focus on quality, so they don't have to fix/replace bags constantly. Therefore, you would think such bags would be less likely to fall apart when away from home.

That said, you have a problem no matter what when a bag breaks away from home. Whether that's a bag with a limited warranty, like Tumi, or an unlimited warranty, like B&R or Red Oxx, doesn't change things. The difference is that the Tumi will cost a fortune to fix/replace, and the B&R or Red Oxx won't.
