HEAT-X Crew Neck Long Sleeve Shirt Retail Price: ¥5049 Purchased at the sporting goods store Sports XEBIO, but I am selling it because I haven't had a chance to wear it. It has never been tried on and is completely unused. This is a functional innerwear that absorbs sweat and generates heat. HEAT-X is a moisture-absorbing and heat-generating material that absorbs moisture from the body and generates heat. It has the function of suppressing humidity inside the clothing and keeping it dry at all times, so it is comfortable.
