Treets Hittepit Elongated has an insulating effect that ensures that heat is retained for a long time and is released very slowly to the environment. In contrast to the hot water bottle, heat wick does not withdraw heat from the body after cooling. Heat pit molds itself to the body and is a 100% natural product. This pillow can be used in bed during cold winter evenings, with muscle or stomach pain, with back or neck complaints. The heat pit is also ideal for hand or foot massage and where the mobility of the muscles needs to be activated. Heat pit can also serve well as a cold compress. In that case, put the pillow in the freezer or in the refrigerator.
