BS Fine Premium Waist Warmer L Size Black [Product Condition] New, Unused [Product Description] The BS Fine Premium Waist Warmer is an item that gently warms your abdomen and lower back just by wearing it. It uses a unique premium fabric, providing a more flexible and comfortable fit, and allowing you to feel natural warmth. It's useful year-round, from summer air conditioning対策 to winter cold対策. Rather than the fabric generating heat, the far-infrared effect of the natural mineral "Black Silica" gently accumulates body heat and maintains a comfortable temperature. It's breathable and can be used comfortably even while sleeping. All BS Fine products are made in Japan. With careful sewing by skilled craftsmen, we use a unique technology that stretches the seams, allowing for a comfortable fit without constriction.
