I think the Challenge bag is so lovely...and because my seat is kinda low, a small bag wouldn't rest on my rack...but how much can a gal carry in one?

I carry: keys/cell/multi-tool/gloves and of course a snack. Um...some grease, a small notebook and pencil. Camera...

I think I just outgrew it...

I'll stick with my Carradice round pack --ebay--
