Tip

Someone sent me a shipping kit once that had unique cool packs.....

They are similar to bubble wrap except the bubbles in this case are gel filled.  They are sized perfectly to fit underneath a cool coat.  I keep them in the freezer.  Once removed they will stay frozen for about an hour if kept under a wet cool coat.  I have never looked for more but they are made by a company called Cryoflex.  They work amazingly well for group showing.
