The U Shape Hot Water Bag is designed in such a way that it can be comfortably laid around the neck. The silicone sleeve is filled with water and heated up in the microwave oven for three minutes. The bag is then put into a knitted fabric sleeve. It also keeps the water at its temperature and produces comfortable haptics in the throat and neck area. With an additional knitted ribbon, the bottle is fixed in the chest area, and the user is able to move around freely.
