I usually carry my multi-tool, which has everything needed for a quick fix. A small air pump, tire levers, spare tube, some TP, soapless hand cleaner, LIP GLOSS, (very important)a choc. bar, cell phone, digital video camera...and sunscreen if needed.
Geez, I thought I carried light until I wrote it all down.... and I seem to be missing some stuff that you gals have.....guess it's time for a new Camel Bak!!!
