This is the popular BAKUNE sweat item from TENTIAL. Worn about 3 times. There are no noticeable stains or damage, and I think the condition is good. These are functional pajamas and loungewear that use special fibers to promote blood circulation and help recover from fatigue. Blood circulation is important for recovery from stiff shoulders and lower back pain, so this is a highly anticipated item. New ones are quite expensive, so how about starting with a good-quality used one? ^_^ The color is white. The size is a popular XL. I've attached a screenshot of the size chart.
