I bought this online for over 10,000 yen. I sweat like crazy in it. It's good for dieting. I don't need it anymore, so I'm offering it to someone who wants it. By the way, I've only used it 3 or 4 times. In winter, I would be drenched in sweat just from walking the dog while wearing this. It's still usable, so I've been keeping it at home. I was keeping it because it felt wasteful to get rid of it. I've added more photos.
