Features "Re-Optimum" is a collection developed specifically for recovery of the body using KODENSHI technology. This track jacket is useful not only for everyday use, but also for sports expeditions and travels. KODENSHI technology offers a long-lasting natural warmth generated by the user's own body temperature (far infrared rays emitted from the human body). It can maintain "the warmth close to the body temperature," which humans require to relax and feel comfortable. Made of fabric with excellent stretch for a comfortable fit. Processed for wrinkle-resistance. A simple track jacket design with waist pockets for a clean look. Can be worn like a windbreaker all year round. *The Re-Optimum series was developed with the cooperation of Dr. Norinaga Shimizu, Professor Emeritus of Osaka Public University, who has been researching environmental adaptation and sleep for over 30 years in the field of health and medical science.
