When on the Jelly Belly tour you have to wear a hat; the principle reason is for health and safety. They don’t want any hair or fur going into the candy mix. I think it is also helps with identifying those who are on the tour and those who work at Jelly Belly. The hat was small enough so that I was able to wear one, although as I am covered in the fur I wasn’t too sure what I was meant to do for my paws and face.
