A hot & cold wrap usually contain a gel pack or similar and are ideal for applying cold to specific areas as well as compression. If you have a whole joint injury such as an ankle sprain or knee sprain which involves swelling of the entire joint then a knee wrap or ankle wrap covering the entire joint will be most suitable as they will provide compression to help reduce swelling. If the injury does not involve swelling or is on a small area such as a single tendon then a simple ice pack or wrap will be suitable.
