Features Re-Optimum series developed for recovery using KODENSHI technology. This collection is loved by top athletes in various sports. The KODENSHI technology is characterized by the long-lasting natural warmth produced by the wearer's own body temperature (far infrared rays emitted from the human body). It can """"keep warmth close to body temperature"""" necessary to relax and stay comfortable. Items made with paper-fibers have excellent moisture absorption properties, fresh dry feel, and comfortable; perfect for hot and humid summers. Made from a blend of cotton and polyester for a nice texture. Can be worn comfortably even with a significant difference in temperature between hot outside and air-conditioned indoors. Slightly relaxed silhouette. The collar is designed with a binder that retains its shape even after repeated washing and flexes the stretch of the fabric. Great not only as loungewear but also as post-workout wear. The cotton is organic cotton (100% organic materials). Partially made of recycled yarn.
