I have an older Crumpler back pack. I carried it everyday for three years before the zipper gave out. The rest of the bag is still in pretty much new condition. I'm going to put a new zipper on it eventually. Incredibly comfortable bag.

I had the team player which used to be their largest backpack. I didn't feel like it was too big, in fact the main reason I haven't fixed it yet is because I bought a larger bag.
