This is a Mizuno t-shirt. It's made of mesh material, so it's light and feels cool. 100% polyester I bought it in a hurry, but I only wore it once and it's now too small. It's in almost new condition and is beautiful, but it has been worn once. I have carefully inspected it, but as it's a personal inspection, there may be oversights. Please refrain from purchasing if you are concerned.
