Gray IONDOCTOR belly band with warming effect. Also highly recommended as a neck warmer. - Brand: IONDOCTOR This highly popular, thin supporter can be worn like underwear, made from 100% cotton fabric processed with natural mineral powder. Its thin design makes it perfect for wearing at work or when going out. It protects your abdomen and lower back from the cold. For lower back pain, menstrual pain, poor gastrointestinal function (such as irritable bowel syndrome and constipation), obesity, and "abdominal care" for pregnant women! Use it all year round, in spring, summer, autumn, and winter. In addition, because it is made of fabric processed with natural mineral powder, it does not easily absorb odors from sweat, so it does not need to be washed frequently. Simply air-drying it after taking it off is sufficient. Recommended not only for the cold season but also for protection against air conditioning in the summer!
