In the sports and healthcare sector, Kobayashi Sewing Industry develops and manufactures innerwear and support products designed for specific applications, including body support and use during physical activity.

Depending on the product requirements, the company can incorporate specially treated materials, including antibacterial and deodorizing fabrics, as well as protective features intended to help reduce the impact of falls or bumps. Support is available from prototype development through OEM production.

The company also invests in the development of proprietary materials and original products. In 2015, it developed PEACHTECH®, an innerwear material designed with wearer comfort in mind. Its original product lineup has since expanded to include Hyakunen Shorts, Up Girdelly, Fujiko, Kaifukuband®, and Beppin Backrest Belt.
