I have also used Make-up bags - usually they have a zipper part on the top part where I keep everything associated with the shot(alcohol, band aides,etc)
The bottom portion is big enough to carry the Cortef, Florinef, Advil, then in a ziplock bag I have the Emergency paperwork. when I know that I will be out and about in the car all day-I put Ice packs on the very bottom with a towel on top of it-this will allow the towel to absorb the sweat from the ice packs.
Getting ready for school this year I ran across some small lunch bags that were insulated. It's so funny that this subject came up because for years I have complained that there is no bag with insulation for parents to carry meds. Told my husband about a year ago that CARES should come up with something for CAH'ers
God Bless
