HARAMAKI is a comfortable underwear for all year round. It keeps you cool in summer and warm in winter. It gives a warm comfort to your belly. HARAMAKI is made of natural materials, such as silk and cotton, and very gentle to skin. Silk is able to hold a lot of air among fibers. This feature helps it comfortable to wear at any time of the year. As silk does not stand well against water and friction, combining with cotton makes it more durable. To avoid restricting body movements, we use the material which gives the superior stretch to cover your belly comfortably. Recommended to use during bedtime and daytime as it is thin to wear. This is a perfect way to keep your belly warm in any season.
