178cm,69kg. I bought XL at first but it's too big. Then i returned it and get 8400yen only, what should i say, damn it. Why doesn't this page provide a more precise size graph? However, i bought L instead of it. ちょうどいいです。But why can't i get full money or just change the size? I am so sad about that. But the jersy is definitly a nice product. It's right choice to by izumi.
