The Re-Optimum series utilizes photo-electronic technology developed for recovery, loved by top athletes across various sports. The photo-electronic technology features natural warmth generated by the wearer’s body temperature (far infrared rays emitted from the human body), ensuring sustained comfort. It helps maintain warmth close to body temperature, allowing for a relaxed and pleasant experience. The sweatshirts made from soft pile fabric balance functionality and comfort, with a surface crafted from organic extra-long cotton that offers a smooth texture and clean look. The inner layer incorporates photo-electronic technology and is enhanced with Maxi Fresh to reduce unpleasant odors caused by sweat. The pile is designed using special twisted yarns, creating a fluffy soft touch. The relaxed pattern design envelops the body gently for a comfortable experience. The silhouette offers moderate roominess, and the pivot sleeves provide ease of movement for the arms. With flat seams for a smooth feel against the skin, considerations have been made for comfort. To minimize deterioration over time, polyurethane material is not used. To reduce environmental impact, organic cotton and recycled fibers are incorporated into some materials. Matching sweatpants (model number: GC43342) are recommended for a complete set-up. *The Re-Optimum series was developed with the collaboration of Dr. Kyoe Shimizu, a professor emeritus of Osaka Metropolitan University, who has over 30 years of research in health science related to environmental adaptation and sleep.

Reviews
Many opportunities to be active
I liked the color of TG at the store and purchased it. Compared to regular sweats, the fabric is soft and comfortable to wear. Moreover, it is warm thanks to the light electronics. It's an item that you just can't help but pick up. The size was also good, not too big or too small.
Black Oolong
I love the shape and texture!
I really liked the shape and texture, so I purchased it again in a different color!
I was glad I bought the first one in black, but if you wash it roughly, it will start to pill after about three washes. After about five washes, it starts to show the wear of being worn for about two years. Pilling happens quickly if it's not cotton.
Let's wash it gently in a laundry net!
