This is a Mizuno Diamond Hero (52LB-726) T-shirt. It's a men's size, but I think women can also wear it comfortably. ◆Product Suitable for various sports such as amateur baseball, fashion, baseball, soccer, training, muscle training, dieting, and marathons. ◆Condition I bought it new about 15 years ago. I wore it about 10 times for exercise, wearing an undershirt. And I've washed it as many times as I've worn it. After that, I've stored it at home. Please refrain from purchasing if you are sensitive to used items. ◆Material 100% Polyester ◆Size M size Width 48.5cm, Length 61cm.
