Utilizing light electron technology, the Re-Optimum series is developed for recovery. This collection of T-shirts, loved by top athletes in various sports, has been crafted with a cotton-like texture for an urban feel. The light electron technology harnesses the natural warmth generated by the wearer's body temperature (far infrared rays emitted from the body), providing sustained natural warmth. It ensures that you can maintain a temperature close to your body for a relaxing and comfortable experience. By using different knitting structures on the surface and skin side, the distinct functions coexist. The surface is made from organic extra-long cotton (100% organic material) woven in a high gauge for a smooth texture with elegant luster, drape, and appropriate elasticity. On the skin side, quick-drying polyester and the comfortable stretch of Solotex are utilized to deliver a lightweight feel. Designed to be worn easily on its own with a substantial thickness, it's suitable for all seasons. The standard silhouette easily adapts to various outfits. It's designed not just for relaxation scenes but also for urban use. *The Re-Optimum series is made possible through the collaboration with Dr. Yoshinaga Shimizu, a professor emeritus at Osaka Public University, who has been researching environmental adaptation and sleep for over 30 years in the field of health science.*
