Features
A lifestyle-ready T-shirt from the Re-Optimum series, designed with KODENSHI technology to support comfortable recovery time, finished with a cotton-like look suitable for everyday wear.
- Part of the Re-Optimum collection, developed with KODENSHI technology and favored by top athletes across various sports for post-activity comfort.
- KODENSHI technology utilizes the wearer's natural body heat to help maintain a gentle, stable warmth close to body temperature, supporting relaxed and comfortable wear.
- Dual-knit construction separates functions between layers: the outer surface uses high-gauge organic extra-long staple cotton (100% organic content) for a smooth touch, elegant sheen, natural drape, and moderate resilience.
- The inner layer combines quick-drying polyester with stretchable Solotex fibers, delivering a dry, smooth feel and comfortable elasticity against the skin.
- Balanced fabric weight makes it easy to wear on its own while remaining suitable for all-season use.
- Features a clean, standard silhouette that pairs effortlessly with a wide range of outfits, from relaxed settings to everyday urban styling.
- Developed with academic insight from long-term research in environmental adaptation and sleep science, contributing to a thoughtfully engineered comfort-focused design.
*The Re-Optimum series was developed with the cooperation of Dr. Norinaga Shimizu, Professor Emeritus of Osaka Public University, who has been researching environmental adaptation and sleep for over 30 years in the field of health and medical science.
