Anyone have a mussette? Not a messenger bag, but an old fashioned canvas or cotton bag with long straps to wear over your head. It seems like such a brilliant old-school solution for carrying a lunch or a few small groceries. When you're not using it, you just roll it up and stick it in your jersey pocket.
The problem is that the only one I can find anywhere is on the Bianchi site:
I don't have anything against Bianchi, but I don't want to pay $19 for a little cotton bag. If you have a cheaper, better alternative, I'd love to hear where you got yours.
