I purchased this at a sports shop while traveling. I bought it with the intention of giving it to someone, but I haven't had the opportunity to give it away, and it's been over six months, so I'm putting it up for sale. I bought several, and I've been selling different styles until recently, but this is the last one. Size: S (Seems to correspond to a Japanese size M) I think it's a good deal as it's sold for around 27,000 yen on Rakuten and other sites! ↓ Quoted from the following site: This is a tri-suit with high cooling effect, excellent aero effect, and lightweight, flexible support functions that prevent muscle vibration.
