Featuring a stretched, tubular shape this hot water bottle provides excellent heat coverage to keep you warm during the coldest nights. Due to the unique, extended shape, it can heat a greater area at once, whilst the soft outer jacket adds a layer of comfort and protection. Proven to help improve circulation, relax muscle tension and soothe aches & pains, the elongated flexibility of the bottle is ideal for providing heat to awkward-to-reach areas, such as the back, neck and shoulders.
