《What is Wearable Ganbanyoku BS-FINE?》
BS-FINE is a functional material made by encapsulating the natural mineral black silica, popular in ganbanyoku (hot stone spas), within polyester fibers measuring 3 micrometers in diameter.
By reducing the mineral to 0.3 micrometers, the surface area is increased, further enhancing the mineral's efficiency.
While conventional warm materials generate heat or rely on thickness for insulation, BS-FINE warms the body itself with the far-infrared rays from the natural minerals within the fibers, even though the fabric is thin.
Furthermore, unlike conventional warm materials that can feel stuffy, BS-FINE provides a comfortable warmth that is dry and non-sticky, allowing for year-round use.
Since the minerals are encapsulated within the fibers, their functionality remains unchanged even after washing.

〈About Natural Mineral Black Silica〉
Black silica (scientific name: Graphite Silica), mined in Kaminokuni Town, Hiyama Subprefecture, Hokkaido, is believed to be formed from diatoms that accumulated on the seabed over hundreds of millions of years. It is a precious natural mineral containing many natural minerals that emit far-infrared rays at room temperature.
It has gained popularity, especially since the ganbanyoku boom, and is used in many ganbanyoku facilities both domestically and internationally. Black silica has also proven effective not only in health-related fields but also in environmental applications such as water purification, and its potential for further application development in various fields is highly anticipated.

〈Scientific Data for BS-FINE®〉
In spectral emissivity measurements (far-infrared measurement method), BS-FINE® yarn recorded values exceeding 10% across the entire spectrum compared to standard polyester fibers.
Additionally, in our heat storage performance tests, it recorded an astonishing plus 3 degrees Celsius compared to cotton.
