Dose it have to be something that keeps a person warm? I've been mildly obsessed with making these pyrex carriers lately. They are reversible, washable and really cute. Ive got them sized for the 8x8 or round pan and a big behemoth one for the 9x13 pans. The big one is 26x26 so you can really carry anything in it.
