I'm borrowing a Mizuno tag. Ameyasan also sews Mizuno sauna suits, and this is a sauna suit made of the same material. It was cheaper because the tag isn't Mizuno. I was told this by the boxing gym chairman. I've worn it a few times. The inner lining isn't deteriorated. It's a short-sleeved, short-pants type, but you sweat incredibly. I also have a long-sleeved, long-pants type. Boxing Diet
