This pack has lasted me for over two years of tough use. I have used it everyday as my "guy purse" to take my notebook (now netbook) and a few small books, magazines, and computer peripherals almost everywhere I go: work, travel, pool, etc. Its interior lining is starting to show some wear. But that's not surprising given the abuse it's received. I may order another one or two just to make sure I will always have a backup bag like this.
