Our medium-sized heat pack is designed to sit around the neck, over the shoulders and upper back. It measures 46cm in length and 27cm in width, weighing 1.6kg. It's our most popular item, and for good reason. Simply heat it in the microwave for 3-3.5 minutes for instant relief from pain and stiffness. Filled with Australian lupin seeds, it's virtually odorless when heated and safe for those with gluten sensitivities. Our double-sided design features designer cotton on one side and soft corduroy on the other, available in a variety of fabric options. It can be used as a hot or cold pack, providing chemical-free pain relief.
