BS Fine, the "wearable bedrock bath," is a functional material that contains black silica, a natural mineral popular in bedrock baths, encapsulated within its fibers. Simply wearing it gently warms the body. The fabric is non-heating, so it will not heat up beyond body temperature. It maintains a comfortable temperature without overheating, so you will feel neither too cold nor too hot. It is comfortable all year round, spring, summer, autumn, and winter. The effect remains the same even after washing. In fact, some customers who have purchased BS Fine say they don't immediately feel the warmth. This is because BS Fine doesn't warm you up by generating heat from the fabric like other winter warming materials. BS Fine naturally warms the body through the infrared rays of the minerals in the fibers, and the fabric stores that body heat, maintaining a constant temperature and assimilating it with your body temperature. Because the warmth is so natural, some people find it hard to feel it. However, it does warm the body well, and it's dry and not stuffy in the hot summer, and you won't get cold from sweating even in air conditioning. It's toasty and cozy in the cold winter, and once you try it, you won't want to let it go. All BS Fine series products are made in Japan. Each piece is handmade by artisans.
