The Re-Optimum series, developed using photonic technology for recovery, features a basic sweater made from a blend of natural wool fibers and photonic elements. By finishing a polyester blend with wool and photonic technology in a plated jersey knit, it harmonizes two functions. The surface allows you to enjoy the luxurious texture of wool while also providing warmth and moisture management inherent to wool. The inside is knit to harness the properties of photonics, which preserve natural warmth generated by the wearer's body temperature (far-infrared radiation emitted by the body). This helps maintain 'warmth close to body temperature,' essential for relaxed and comfortable experiences. With a slightly loose and relaxed silhouette, this mid-weight type can be worn across a wide range of seasons. Its simple design, finished in a nice-looking mid-gauge knit, makes it suitable not only as loungewear for recovery but also as an ideal option for athletes during travel, offering a polished yet comfortable style as three-mile wear. Hand washing at home is possible. *The Re-Optimum series was developed with the collaboration of Dr. Yoshinori Shimizu, Professor Emeritus of Osaka Public University, who has over 30 years of research in environmental adaptation and sleep in the field of health science.
