Crash the party wearing the Inflatable Fan-Operated Chicken Costume. You'll be the centre of attention and every party guest will be delighted with this comical, bright and unforgettable costume! This durable, one-size-fits-all costume is constructed of an extremely light polyester material called terylene. This high quality material keeps you cool and free of perspiration. Included with the costume is a compact fan unit that keeps the costume inflated and never lets it droop. The battery pack clips to your pants or belt under the costume. The batteries will keep you "inflated" for at least several hours.
