I have a crumpler wonder weenie and I like it ok. The material is a little scratchy feeling, and it's that same texture that seems to pick up a LOT of lint. But, that's not really effecting the perfomance any. It does what I need it to.. I'm not a courier so I dont carry packages in it or anything, just use it to commute as my old backpack hurt my shoulders when I rode with it.

I'm seriously thinking about making my own.. although I've never sewed a thing in my life... some friends of mine are practically seamstresses, except they're men. Gonna see if they can help me. Just gotta score some cordura.
