There’s nothing like a warm substance for soothing aches and pains, and a filled rubber hot-water bottle is one of the older and most trusted methods of accomplishing this. In fact, some rubber hot-water bottles can get and stay too warm; in which case, it’s smart to purchase a rubber hot-water bottle that includes one or more knit covers.
The best rubber hot-water bottle is the Transparent Bottle with Knit Cover. This is one of the most secure rubber hot-water bottles available, and with such a wide mouth, it’s easy to fill, empty and refill.
