I bought a Wenger Swissgear backpack when I was (probably) around 14. I'm now 21, and I still use it. It's capacious, got heaps of pockets and I've taken it with me throughout Europe. Oh, and it's got a carabiner attached to it, for some reason. And it's sturdy as. It's like the Panasonic Toughbook of backpacks.

So, yeah. Wenger are awesome. I like their stuff.
