A medium-thick type that can be worn in a wide range of seasons.
Leveraging photonic technology, the Re-Optimum series has been developed for recovery purposes. This basic cardigan features a knit that combines natural fiber wool and photonic technology. By finishing polyester with wool and photonic technology in a plating jersey knit, both functionalities are achieved. The surface offers the luxurious texture of wool, along with the inherent thermal insulation and moisture-regulating properties of wool. The inner layer is knitted to incorporate photonic technology. The photonic technology utilized generates natural warmth sustained by the wearer's own body temperature (far-infrared radiation emitted from the body). This provides a necessary warmth that is close to body temperature, allowing for relaxation and comfort. With a slightly loose, relaxed silhouette, this mid-weight garment can be worn across various seasons. Its simple design crafted in a clean-looking mid-gauge knit not only serves as loungewear for recovery, but also excels as travel wear for athletes and leisurewear with a neat appearance. It is machine washable at home. *The Re-Optimum series was developed with the cooperation of Dr. Yoshinaga Shimizu, a professor emeritus at Osaka Metropolitan University, who has over 30 years of research in the fields of health science, environmental adaptation, and sleep.
