I'm trying to keep my load as light as possible. I'm looking for some ideas for a tiny emergency tool bag to hold:

• tire lever
• 3 allen keys
• 1 tube
• loose patches

Previously, I've been just been rubber banding them together, placing into a ziploc bag, and crudely strapping it onto the underside of the downtube with velcro straps--but it's just not secure enough for my tastes. I'm thinking a tiny cloth bag with a zipper, maybe with some webbing loops on it so I can zip tie it to the downtube (along the shifter cables). It doesn't really need to be a bike specific bag, I'm not sure what to look for though. A pencil case?

Also, if anyone knows of a good butt bag (fanny pack) I can use for just a few items I'd occasionally want to grab while riding, cheap, simple, not too big, comfortable?
