ive killed a dakine and an older classic made in the usa backpack; i ripped and derailed the zipper of the dakine and derailed the zipper and ripped the bag of the classic one. Both died within a 2 year period of time, which is ridiculous. I only carry about ten pounds of books at a time (at most) anyway. I seriously need a backpack that I can depend on, and i don't want to spend more than 70. I thought dakine, making only backpacks, would be good but that proved to be wrong...
