"Wearable Ganban-yoku" "Wearable Ganban-yoku" BS Fine is a new material that encapsulates natural mineral "Black Silica" reduced to a diameter of 3/10,000mm within polyester fibers of 3/1,000mm diameter. Because the "Black Silica" is sealed within the fibers in a core-sheath structure, the mineral will not dissolve or peel off even after washing. Furthermore, "Wearable Ganban-yoku" BS Fine warms the body itself with "Black Silica," so it is a dry, warm material that does not get stuffy. Even though the fabric is thin, it warms you to the core of your body. You can comfortably use it throughout the four seasons without getting stuffy even in hot places.
