Get cosy with our Navy Chunky Knit Long Hot Water Bottle. The extra long length has been designed to wrap around your shoulders, tummy or along the length of your body for more coverage than a standard hot water to provide additional warmth and comfort. Heat therapy is a great natural way to soothe aches and pains, ease menstrual cramps or soothe and relax the mind & body in preparation for a restful nights sleep.
