My current backpack is nearly 10 years old. It's an AlphaServer-branded backpack I got when I was working at Compaq. The straps are frayed around the shoulders, there's at least two spots where the zipper teeth are bent or smushed so you have to work the zipper carefully around those, and last night one of the bottom straps broke and had to be re-attached through careful use of knots, the strap adjuster clip, and friction. It won't be long before that fix won't work anymore, either.
I don't want to get a new backpack.
