Brand new, unopened Wearable Ganban-yoku (Rock Bath) BS Fine Leggings Size: LL Color: Black Wearable Ganban-yoku BS Fine is a functional fiber that encapsulates Black Silica, a popular natural mineral used in rock baths, within polyester fibers. The far-infrared rays from the mineral within the fiber warm the body, and the fabric stores and maintains that body temperature. It provides a light warmth, and you can wear it comfortably throughout the year without feeling stuffy or sticky. It is not thick, so you can wear it under pants.
