Utilizing photonic technology developed for recovery, the Re-Optimum series is a collection of T-shirts favored by top athletes across various sports. By using cotton on the surface, these shirts blend seamlessly into urban settings. The photonic technology featured allows for sustained natural warmth generated from the wearer’s body temperature (far-infrared radiation emitted by the human body). This enables the shirt to maintain a warmth close to body temperature, essential for relaxing and comfortable wear. The different knit structures on the surface and skin side coexist to enhance their respective functions. The outer layer features a soft cotton fabric (100% organic material) for a natural texture, while the inner side employs quick-drying polyester and comfortable stretchable Solotex, achieving a pleasant feel and fit. With a thicker fabric that is easy to wear alone, this T-shirt is suitable for all seasons. Its oversized silhouette looks great on adults, with long sleeves designed for both relaxation and everyday urban use. *The Re-Optimum series was developed in collaboration with Dr. Yoshinobu Shimizu, an honorary professor at Osaka City University, who has over 30 years of research in environmental adaptation and sleep within the field of health and medical science.

Reviews
comfortable
I am 178 cm tall and wore size 3, and it was a perfect fit for my broad shoulders and good build. The sleeve length was about to reach my watch on my left arm.
Not only as loungewear but also because it looks elegant, I think I could wear it out in the city.

comfortable
I tried it on and purchased one size smaller than my usual size 4 for the sweatshirt. Even though I downsized, it was still loose and felt comfortable, so I think I can wear it in any season.
