Hot water bottle for soothing hours On cold evenings, a hot water bottle is the best way to banish the cold from your bed. Never again ice feet. The XXL rubber hot water bottle holds up to 2 litres of hot water. You can also use it for discomfort in the abdomen, back or neck. The soothing warmth also relieves tension. The right size for small and large. The bottle is securely closed by the cap. Thanks to the lamellae, the odorless rubber has a good grip even without a cover.
