High-performance ceramic vest that provides lasting warmth with room-temperature far-infrared rays. The high-performance ceramics and unique 5-layer structure warm the body from the core. Proven effectiveness through thermography tests. Recommended for those with "stiff shoulders and lower back" and "those who feel cold easily." I believe the usage frequency was low, but there is a sense of use, so I marked it as having some scratches and dirt. Although it's labeled as size S, it can be used as a women's size M. Size (S size) Chest: 80-88 cm Length: 64 cm Shoulder width: 40 cm Hem circumference: 102 cm Hem slit: 4 cm
