Tanaka has its own factory and research institute in Gifu Prefecture, where they developed "Tough Silon® (silicone)" aiming for the physical properties of the human body. They have carefully considered not only the appearance but also the hardness, stretch, wrinkling, and even the feel when a needle is inserted. ■ Joint research with Gifu University School of Medicine: In addition to Tanaka's knowledge and technology, the expertise of the Gifu University School of Medicine has been added to complete a structure that allows for movement closer to the muscles of the knee. This supporter's biggest feature, called the "Spider Silicone Structure," supports knee bending and straightening with its knee pattern. Medical school professors actually used it as monitors, and the structure was achieved through repeated performance evaluations and improvements. ■ Comfortable fit that doesn't constrict too much: By using "Tough Silon® (silicone)", there is less constriction than with general supporters, making it easier to move, and comfortable to wear all day long. We aimed for a supporter that can be worn all day. ■ Carefully selected fabric: The fabric is soft to the touch, thin, and breathable. It can be used regardless of the season. The inside of the fabric has a non-slip treatment to prevent slippage. Also, because the fabric is thin, it is less noticeable under clothing and does not restrict clothing choices.
